This article answers the question what if my carry on is one inch too big for the airlines I am flying?

As a longtime traveler, I have many hacks to make sure my carry-ons and personal items are the right dimensions while carrying everything I need.

When you’re in a pinch and your carry on is too big for your flight restrictions, here is what you can do.

Let’s dive in.

Here’s What to do When Your Carry on is Too Big

You will either need to pay an oversize fee, or you will need to transfer some things from your carry on to your personal item.

The trick is using a carry on with soft sides, rather than a hard-sided suite case.

This allows you to transfer items between your carry-on and personal item (purse, small backpack, laptop bag, diaper bag, etc).

Most airlines, from American Airlines to Alaska Airlines, allow a free personal item.

So when you head to the airport, make sure your personal item has extra space.

3 Tried and True Fixes for Oversized Carry Ons

1. Always bring a small personal item, even if it is an empty bag inside of your carry on. This way, you can transfer items from your carry on to personal bag if your carry on is too large.

If you’re at your gate and didn’t bring one, go to the nearest gift shop or foot stall and ask for a plastic bag. This can act as your “personal item” to move items from carry on to personal.

2. Use the bag measurement tool at airport check in counter. This saves you a scramble when you’re at the gate boarding your flight. If needed, you can repack your carry on before your flight boards.

These measurement tools are at gates too, but you’ll probably give yourself away by measuring your bag. So, walk a few gates down and measure your bag there.

3. Always use a soft sided carry on bag, or purchase a hard sided carry on bag that fits airline carry-on dimensions. A soft sided carry on bag allows you to adjust what you’re carrying so you can fit the bag into the bag measuring tool at the gate.

If you didn’t bring a soft sided carry on, wait to be the last to board. On full flights, airlines might ask customers to check their bags if the overhead bins are full. This is your best bet for avoiding baggage fees if your bag is going to be obviously too large and flight attendants will notice.

Here’s The Download on Airline Size and Weight Restrictions for Carry Ons

If you understand why airlines have size requirements for luggage you can plan how to pack and avoid a carry on that is too big.

Both international flights and domestic flights in the US typically allow a personal item. This is meant to be stowed under the seat in front of you.

Airlines also allow carry-ons, typically a small rolling suitcase, duffel bag, or backpack. These may be stowed below the seat front, but may require the overhead bin storage.

Airlines don’t like when passengers bring oversized carry-on baggage, perhaps because the flight runs out of space in the overhead compartment for other passengers to stow items.

The gate agent may actively check bags as you board the plane. If you’re feeling like risking it with your carry on being one inch too big, check online to see how restrictive your airlines typically is with a larger bag.

Just like maximum size, the same goes with weight restrictions. The carry-on weight limit will differ by airline and is usually under 25 pounds. However, it’s not as common to incur additional fees from a heavy bag since most airlines won’t check at the gate.

If your bag is oversized, the most likely scenario is you’ll be asked to do a gate check of your luggage to your final destination.

Various airlines offer a free carry-on bag depending on fare type. So, always check with the airline you are flying. Budget airlines are notorious for extra fees, so be aware of this before booking your flight.
