Carry-on luggage is all about convenience, so be sure you pick the right size for the type of travel you do. Not all airlines play by the same luggage rules. Most US-based airlines have similar size restrictions, with the average carry-on size around 22in x 14in x 9in. But this changes with international airlines. Bring a standard carry-on bag onto an international flight, and you may suddenly find your carry-on getting checked.
Most carriers outside the US have different carry-on size limits designed for their overhead bins, which can be shorter, wider, or smaller overall. The guide below will help you pack the right bag, whether you fly internationally every trip or just want a bag that adapts to both domestic and international travel.
What's the Difference Between Domestic and International Carry-Ons?
International carry-on bags are slightly smaller in length but wider than standard domestic carry-ons. While international carry-on sizes are around 21.5in x 15.59in x 9in, the biggest difference is the allowed weight. Most domestic airlines don’t publish weight limits for carry-on baggage. Some international airlines impose weight limits as low as 15 pounds.

When a Domestic Carry-On Makes Sense
If you primarily fly within the US, then a domestic carry-on may be the best choice, as it offers a bit more packing space while meeting US carriers’ size restrictions. Your 22-inch-tall domestic carry-on bag should fit easily in the overhead bin stacked on its side, with the handle easily grabbable.
When an International Carry-On is Better
If you regularly fly within the US and internationally, then an international-sized carry-on bag is a safer choice. Sacrificing a little bit of packing space will pay off if you end up on a plane that doesn't allow the slightly taller domestic-sized bags. If your carry-on is oversized, it gets treated like checked luggage, and you could be charged extra fees.

How to Check Airline Carry-On Size Requirements
Confirm how big a carry-on can be with each airline you plan to fly. Most have similar requirements with minor variations, but it’s always best to double-check with the individual companies, in case regulations have changed.

Both Maxlite® collections are available in different colors with companion bags and checked sizes that can be mixed and matched to complement your carry-on.
