  • You also get to bring one personal item, like a purse or a small backpack, that has to fit under the seat in front of you.
  • Alaska Airlines doesn’t have a specific weight limit for carry-on bags, but you still need to be able to lift it into the overhead bin yourself.

Decoding The Official Size Of Carry On Luggage For Alaska Airlines

Standard Carry-On Bag Dimensions

Okay, so you’re planning to fly Alaska Airlines and want to bring a carry-on? Great! It’s important to know the exact size limits to avoid any surprises at the airport. Alaska Airlines allows one carry-on bag per passenger, free of charge, as long as it fits within their size restrictions. The maximum dimensions for a carry-on bag are 22 inches in height, 14 inches in width, and 9 inches in depth. Make sure to use a bag sizer to confirm your luggage size.

The 45 Linear Inches Rule Explained

What’s this "linear inches" thing all about? Basically, it’s another way of saying that the total size of your bag (length + width + height) can’t be more than 45 inches. So, if your bag is close to the maximum on two dimensions, you’ll need to make sure the third dimension is small enough to keep the total under 45 inches. It’s a simple calculation, but it’s easy to overlook. This rule is outlined in the Alaska Airlines Contract of Carriage.

Why Wheels And Handles Count Towards The Size

This is a big one that a lot of people miss! When you’re measuring your carry-on, you absolutely have to include the wheels and handles. Those extra inches can make a difference, and Alaska Airlines is pretty strict about it. Don’t get caught out by thinking only about the main compartment of your bag. If your bag is over the limit because of the wheels or handle, you might have to gate-check your luggage, and nobody wants that. Here’s a quick checklist to keep in mind:

  • Measure the height from the bottom of the wheels to the top of the handle (when fully extended, if it’s a telescoping handle).
  • Measure the width at the widest point, including any side handles or pockets.
  • Measure the depth, making sure to account for any bulging when the bag is packed.

It’s always a good idea to measure your bag at home before you head to the airport. This way, you can be sure it meets the requirements and avoid any potential issues at the gate. If you’re unsure, use the airport sizers to double-check before boarding.

Understanding The Personal Item Allowance

Alright, so you know about the carry-on, but what about that second bag? Alaska Airlines lets you bring a personal item in addition to your carry-on. It’s pretty useful for stashing things you want easy access to during your flight. Let’s break down what counts and how to make the most of it.

What Qualifies As A Personal Item

Basically, a personal item is a smaller bag that fits under the seat in front of you. Think of it as your sidekick to the main carry-on. It needs to be something you can easily manage and stow away without blocking the aisle or taking up someone else’s space. Here are some common examples:

  • Purse
  • Laptop bag
  • Small backpack
  • Briefcase

Size And Placement Of Your Second Bag

While Alaska Airlines doesn’t always specify exact dimensions for personal items, a good rule of thumb is to keep it under 18 x 14 x 8 inches. This size ensures it will comfortably fit under the seat. The main thing is that it must fit completely under the seat in front of you. This is important for takeoff, landing, and just general safety during the flight. If it’s too big, you might have to gate-check your luggage, which can be a hassle.

Common Examples Of Acceptable Personal Items

To give you a better idea, here are some things people often use as personal items:

  • A standard-sized purse or handbag
  • A laptop case (with or without the laptop inside)
  • A small backpack (not the hiking kind, more like a school backpack)
  • A briefcase for work stuff
  • A diaper bag (if you’re traveling with a baby)

It’s worth noting that while Alaska doesn’t specify a weight limit for personal items, you should still be able to easily lift and manage it. Overstuffing your bag can make it difficult to fit under the seat and might raise eyebrows with the flight attendants. Plus, you don’t want to be that person struggling to shove a heavy bag under the seat!

Navigating Carry-On Weight Restrictions

Does Alaska Airlines Specify A Weight Limit?

Okay, so here’s the deal with weight limits on Alaska Airlines. Unlike some airlines, Alaska doesn’t actually post a specific weight restriction for carry-on bags. That’s right, you won’t find a number listed on their website. However, there’s a catch: you need to be able to lift your bag into the overhead bin without any help. If a gate agent thinks your bag looks too heavy, they might ask you to demonstrate that you can hoist it up there. So, while there isn’t a hard limit, practicality is key. It’s always a good idea to pack in a way that you can manage your luggage easily. The Contract of Carriage doesn’t mention specific weight limits.

Tips For Avoiding An Overly Heavy Bag

Alright, let’s talk strategy. Nobody wants to struggle with a ridiculously heavy bag, right? Here are a few things I’ve learned over the years:

  • Plan your outfits: Think about mixing and matching clothes to reduce the number of items you pack.
  • Wear your heaviest items: Bulky shoes or a heavy jacket? Wear them on the plane.
  • Use travel-sized toiletries: Those full-sized bottles add up fast. Transfer liquids to smaller containers.
  • Consider packing cubes: These can help compress your clothes and keep things organized, but don’t overstuff them!
  • Leave unnecessary items at home: Do you really need that third pair of shoes?

Packing light is an art, not a science. It takes practice, but it’s worth it. Think about what you actually need, not just what you want. A lighter bag means less stress and easier travel. Plus, you’ll have more room for souvenirs!

When Your Bag Might Be Weighed At The Airport

Even though Alaska Airlines doesn’t usually weigh carry-ons, there are situations where it could happen. If your bag looks excessively large or heavy, or if you’re flying on a smaller regional aircraft with limited overhead space, they might ask to weigh it. Also, if the gate agent suspects your bag exceeds a reasonable weight, they might ask you to weigh it. It’s rare, but it’s better to be prepared. Keep in mind that baggage policy can vary.

Here’s a quick rundown of when you might encounter a weigh-in:

  1. Visibly Overstuffed Bags: If your bag looks like it’s about to burst, be prepared.
  2. Smaller Aircraft: Limited space sometimes means stricter enforcement.
  3. Gate Agent Discretion: If they have concerns, they can ask.

So, while you probably won’t have your carry-on weighed, it’s always best to pack smart and be prepared for the possibility. Knowing the carry-on luggage size is also important.

How To Properly Measure Your Luggage

Checking Your Bag’s Dimensions At Home

Before you even think about heading to the airport, grab a tape measure and check your luggage dimensions at home. It sounds simple, but it can save you a lot of hassle later. Make sure you’re measuring the entire bag, including the wheels and handles. Those extra inches can be the difference between smooth sailing and unexpected gate-checking fees. Lay your bag flat and measure the length, width, and height separately. Add them up to see if you’re under the 45 linear inches limit. If you’re close, consider repacking or using a smaller bag. It’s better to be safe than sorry!

Using The Airport Sizers Before Boarding

Most airports have those metal frames, or bag sizers, near the check-in counters and gates. These are there for a reason! If you’re unsure about your bag’s size, use them. It’s a quick and easy way to confirm whether your carry-on meets the airline’s requirements. Just place your bag inside the sizer. If it fits without forcing it, you’re good to go. If it’s a tight squeeze or doesn’t fit at all, you’ll need to adjust your packing or consider checking the bag. It’s a good idea to do this before you get to the gate to avoid any last-minute surprises. These sizers are especially useful if you have a soft-sided bag that can expand.

Special Considerations For Soft-Sided Bags

Soft-sided bags can be tricky because they can expand depending on how much you pack. Even if your bag meets the size requirements when it’s empty, it might exceed them when it’s full. Always measure your soft-sided bag after you’ve packed it to ensure it still fits within the limits. Pay special attention to the corners and edges, as these are the areas most likely to bulge out. If your bag is too full, consider removing some items or using a larger checked bag. Also, remember that even if a soft-sided bag technically fits in the sizer, it still needs to fit comfortably in the overhead bin without obstructing space for other passengers. If you’re planning a trip to Prince William Sound, consider a smaller bag.

It’s always a good idea to double-check your bag’s dimensions, especially if you’re flying on a smaller plane or during a busy travel period. Airlines are becoming increasingly strict about carry-on sizes, and it’s better to be prepared than to face unexpected fees or have your bag gate-checked.

Allowances For Special And Exempted Items

Traveling With Medical And Mobility Devices

When it comes to flying with medical equipment, Alaska Airlines generally tries to make things easier. Essential medical devices like CPAP machines and portable oxygen concentrators (POCs) are usually exempt from carry-on restrictions. You’ll want to contact Alaska Airlines ahead of time to confirm specific requirements and any necessary documentation. It’s also a good idea to bring any prescriptions or doctor’s notes related to your medical needs. For mobility devices like wheelchairs, Alaska Airlines provides assistance with boarding and stowing these items, but it’s best to inform them of your needs when you book your flight. Make sure to check the Contract of Carriage for detailed information.

Guidelines For Infant And Child-Related Gear

Traveling with little ones? Alaska Airlines allows certain child-related items to be carried on board in addition to your regular allowance. This often includes diaper bags, strollers, and car seats. The specific rules can vary, so it’s always a good idea to double-check with the airline before your trip. Here’s a quick rundown:

  • Diaper bags usually don’t count towards your carry-on limit.
  • Strollers can often be gate-checked for free, making travel easier.
  • Car seats may be brought on board if there’s an available seat and they meet FAA safety standards.

Bringing Musical Instruments Into The Cabin

Bringing your guitar or violin on your trip? Alaska Airlines generally allows small musical instruments as carry-ons, provided they fit within the standard size limits. If your instrument is too large to fit in the overhead bin or under the seat, you might need to purchase an extra seat for it. It’s also worth noting that some instruments may be subject to additional fees if they’re checked as baggage due to their size or fragility. Always best to check the special baggage rules before you fly.

It’s always a good idea to contact Alaska Airlines directly or check their official website for the most up-to-date information on these special allowances. Policies can change, and it’s better to be prepared than to face unexpected issues at the airport.

What Happens If Your Carry-On Is Too Large

So, you’ve packed your bag, arrived at the airport, and uh oh… your carry-on might be too big. What happens now? Don’t panic! Here’s the lowdown.

The Process Of Gate-Checking Your Luggage

If your carry-on is deemed too large at the gate, you’ll likely have to gate-check it. This means your bag will be tagged and placed in the aircraft’s cargo hold instead of the overhead bin. You’ll usually pick it up at baggage claim upon arrival. It’s not the end of the world, but it’s good to be prepared. Alaska Airlines reserves the right to check a passenger’s carry-on luggage for any reason, including to ensure it can be stowed safely.

Potential Fees For Non-Compliant Bags

This is where it can get a little painful. If your bag is oversized and you’re forced to check it, you might face checked baggage fees. These fees can vary, and they’re definitely something you want to avoid. It’s always best to check the current fee structure on Alaska Airlines’ website before you head to the airport. Keep in mind that carry-on size limits vary by airline for carry-on luggage.

How To Avoid Unexpected Charges

Here are a few tips to help you avoid those pesky fees:

  • Measure your bag at home: Use a tape measure to confirm your bag is within the 22" x 14" x 9" size limit. Don’t forget to include the wheels and handles! The carry-on bag size limit for flights on all aircraft types is to 22” x 14” x 9” – these dimensions include the wheels and handles.
  • Use the airport sizers: Most airports have those metal frames where you can test if your bag fits. It’s a good idea to double-check before boarding.
  • Pack smart: Avoid overstuffing your bag. A bulging bag might technically be within the size limits, but it could still be flagged if it looks too big. Remember to adhere to the TSA 3-1-1 liquids rule for carry-on.
  • Consider booking a helicopter tour over Hatcher Pass instead of flying commercial.

Ultimately, being proactive and informed is your best defense against unexpected baggage fees. A little preparation can save you a lot of hassle (and money) at the airport. If you are looking for a executive charter service near Anchorage, consider booking a helicopter.

Carry-On Rules Across Different Fare Classes

It’s important to know that Alaska Airlines’ carry-on rules can vary depending on the fare class you’ve booked. What’s allowed for a First Class passenger might be different for someone flying Saver. Let’s break down the key differences.

Allowances For Saver Fare Passengers

Saver fares are often the most budget-friendly option, but they come with some restrictions. One of the biggest things to note is that while you still get a personal item, finding overhead bin space for a carry-on can be tricky. It’s often first-come, first-served, and if space runs out, you might have to gate-check your bag. This means it goes in the cargo hold, and you pick it up at baggage claim. It’s a good idea to pack essentials in your personal item just in case. Always adhere to the requirements of your specific fare class stipulated in the Contract of Carriage.

Benefits For First Class And MVP Status Members

Flying First Class or having MVP status definitely has its perks when it comes to carry-on allowances. First Class passengers typically enjoy priority boarding, which means you’re more likely to secure overhead bin space for your carry-on. Plus, MVP members often get similar priority benefits. This can make a big difference, especially on busy flights. It’s one less thing to worry about when you’re traveling. Understanding these codes helps travelers maximize their miles and elite status benefits explained in Alaska Airlines fare classes.

Policies For Flights With Partner Airlines

If your Alaska Airlines flight is actually operated by a partner airline, things can get a little more complicated. Partner airlines might have different carry-on size and weight restrictions. It’s always a good idea to check the specific baggage policies of the operating carrier to avoid any surprises at the airport. This is especially true for international flights or flights with multiple legs operated by different airlines. To switch to a preferred, more expensive flight, it must be on the same airline and scheduled for the same day as the original booking outlined in Rule 12. For flights operated by partner airlines like codeshares operated by Japan Airlines, different baggage fees and rules may apply.

Comparing Alaska’s Policy To Other Major Airlines

How Alaska Stacks Up Against U.S. Carriers

When it comes to carry-on luggage policies, Alaska Airlines generally aligns with the standards set by other major U.S. carriers. However, there are some key differences. Alaska allows a free carry-on bag and a personal item, which is pretty standard. But, the specific size and weight restrictions can vary. For example, some airlines might have stricter weight limits or slightly different size allowances. It’s always a good idea to check the specific rules for each airline before you fly. According to a study, Alaska Airlines is among the major US airlines ranked by their luggage handling performance.

Key Differences You Might Encounter

Here’s a quick rundown of some differences you might see:

  • Size Restrictions: While Alaska’s size limit for carry-ons is 22 x 14 x 9 inches, other airlines might have slightly different dimensions. Always measure your bag to be sure.
  • Weight Limits: Some airlines, especially budget carriers, are very strict about weight. Alaska doesn’t publish a specific weight limit, but others do. If you’re flying with a heavy bag, this is something to watch out for.
  • Personal Item Rules: What counts as a personal item can also vary. Some airlines are more lenient than others. Make sure your personal item fits under the seat in front of you.
  • Fees: Some airlines charge extra for carry-ons, especially on basic economy fares. Alaska doesn’t, which is a nice perk. Southwest Airlines, for example, provides the most generous carry-on allowance.

It’s worth noting that airline policies can change, so always double-check the latest information on the airline’s website before your trip. Don’t assume that what was true last year is still true today.

Why Carry-On Policies Are Not Universal

Airline carry-on policies aren’t universal for a few reasons. First, different airlines have different business models. Budget airlines, for instance, often charge extra for everything, including carry-ons, to keep their base fares low. Second, the size of overhead bins can vary between aircraft types, influencing the size of bags they can accommodate. Finally, airlines might adjust their policies based on passenger feedback, operational needs, and competition. When comparing Alaska Airlines and American Airlines, key differences emerge for travelers. Alaska Airlines has a smaller route network but offers perks like a free carry-on bag and complimentary seat selection in the main cabin.

Packing Smart: Prohibited Items And Liquids

Adhering To The TSA 3-1-1 Liquids Rule

Okay, so the TSA’s 3-1-1 rule for liquids is something you really need to know. It’s all about keeping things consistent and safe. Basically, all liquids, gels, aerosols, creams, and pastes must be in travel-sized containers that are 3.4 ounces (100 milliliters) or less. These containers need to fit comfortably in a single, quart-sized, clear plastic zip-top bag. Only one bag is allowed per passenger. It’s a pain, I know, but it’s the rule. There’s been talk about changing the TSA 3-1-1 liquids rule, but for now, it’s still in effect.

Items Banned From The Aircraft Cabin

There are certain items you just can’t bring in the cabin, no matter how much you want to. Obvious ones are things like firearms, explosives, and anything that could be used as a weapon. But it also includes things you might not think about, like certain tools, flammable liquids, and even some sporting goods. It’s always best to check the TSA’s website for a complete list of prohibited items before you even start packing. Better safe than sorry, right?

Regulations For Batteries And Electronic Devices

Batteries, especially lithium batteries, have their own set of rules. Generally, you can bring personal electronic devices with lithium batteries in your carry-on, but spare lithium batteries need to be in your carry-on too – not in your checked bag. This is because of the fire risk. There are also rules about the size and type of batteries, so again, check the TSA guidelines. Phone chargers are generally fine in carry-on baggage, but it’s the batteries that need a closer look.

It’s a good idea to put each spare battery in its own separate bag or cover the terminals with tape. This prevents them from short-circuiting and potentially causing a fire. It might seem like overkill, but it’s a simple step that can make a big difference.

Nobody wants to get hit with an unexpected fee at the gate, and that’s a surefire way to start your trip off on the wrong foot. Just remember the main dimensions, 22 x 14 x 9 inches, and don’t forget to include the wheels and handles when you measure. If you stick to that, plus your one personal item, you should be all set. Have a great flight!

Frequently Asked Questions

What is the exact size for a carry-on bag on Alaska Airlines?

For Alaska Airlines, your main carry-on bag can’t be bigger than 22 inches tall, 14 inches wide, and 9 inches deep. This measurement is important because it includes every part of the bag, even the wheels and handles. Make sure your luggage fits these numbers to avoid any issues at the airport.

Can I also bring a personal item? What counts as one?

Yes, you get to bring one personal item along with your carry-on bag. This should be something small like a purse, a laptop case, or a little backpack. The main rule is that your personal item has to be small enough to slide completely under the seat in front of you.

Is there a weight limit for carry-on bags on Alaska Airlines?

Alaska Airlines doesn’t list a specific weight limit for carry-on luggage. However, there’s a practical rule you should follow: you need to be able to lift your own bag into the overhead bin without help. If it’s too heavy for you to handle, it’s probably too heavy to bring as a carry-on.

What happens if my carry-on bag is too big?

If your carry-on bag is too large to fit in the overhead bin, the airline staff will take it from you at the gate. They will check it into the plane’s cargo hold, and you’ll have to pick it up at baggage claim when you land. Be aware that if your bag is over the size limit, you might have to pay a checked bag fee.

Is a backpack considered a carry-on or a personal item?

A backpack can be either your personal item or your main carry-on bag. It all comes down to its size. If it’s a small backpack that can easily fit under the seat, it counts as your personal item. If it’s a larger one, it will be considered your carry-on and must meet the size limits for the overhead bin.

Are the carry-on rules different for Saver fare passengers?

Good news! Even if you buy a Saver fare, which is Alaska’s most basic ticket, you still get the same carry-on allowance. You are allowed to bring one standard carry-on bag and one personal item on board at no extra cost. This is a great benefit that not all airlines offer on their cheapest tickets.

What are the rules for bringing liquids like shampoo or lotion?

When you pack liquids, you have to follow the TSA’s 3-1-1 rule. This means any gels or lotions must be in containers that are 3.4 ounces (100 milliliters) or smaller. All of these little bottles must fit together in a single, clear, quart-sized plastic bag. Each passenger is only allowed one of these bags.

Can I bring my musical instrument on the plane?

You can often bring a small musical instrument, like a violin or guitar, as your carry-on bag. It just needs to be able to fit safely in the overhead bin or under the seat in front of you. If your instrument is too big for those spaces, you might have to check it or buy an extra seat for it to fly in the cabin.
