Carry-On and Personal Item Size Limits for 32 Major Airlines

Every frequent traveler has seen passengers rolling their massive carry-ons and lugging equally large bags and backpacks onto the plane as their “personal item.” So exactly how big can your carry-on and personal item be? The general rule about personal item size is that your bag must fit under the seat in front of you, though some airlines do specify maximum dimensions. Meanwhile, airlines have a wide variety of carry-on size restrictions. Many airlines, especially outside the U.S., also have weight limits for carry-on bags and personal items.

Carry-On vs. Personal Item: What You Need to Know About Baggage Policies

For years, personal items have flown mostly under the radar, but in the new world of basic economy—in which airlines are offering cheaper base fares but charging for carry-ons—more and more people will be traveling with nothing but a personal item.

When you’re traveling on the cheap and trying to pack as much as possible into a very limited amount of space, knowing the rules is vital. Here’s a look at the personal item and carry-on size limits for 10 major U.S. airlines and 22 top international carriers.

A few important notes:

  • The dimensions below reflect length, height, and width, and include wheels and handles.
  • Personal item and carry-on dimensions listed below reflect the size limits for flyers in economy class. (Airlines often have more generous baggage allowances for flyers in first or business class.)
  • If you’re traveling on a codeshare flight, you’ll need to check the baggage restrictions for the airline operating the flight—not necessarily the airline through which you booked.
  • On shorter trips flown on smaller planes, even regulation-size carry-ons may need to be gate-checked. (In such cases, you shouldn’t be charged the normal checked bag fee.)
  • Because carriers can change their rules at any time, it’s a good idea to double-check before each trip.
