Everyday Carry & Travel
Bags, personal items and daily carry gear, with the size limits and measurements that matter before you buy.
Everyday gear has rules you don't see until you hit them, usually at a boarding gate. The guides in this section pull those rules from the official source, put them side by side, and date-stamp them, because airline policies change. Then they show how to measure your own bag the way a gate agent or a sizer box would: packed, with straps and pockets included. Where a published limit doesn't exist, we say so instead of guessing. You'll also find a short list of who a given bag style suits and who should look at something else. Check the airline's own page again before you fly.
Guides in Everyday
Before any bag purchase
Look for outside dimensions
A bag's listed size may leave out wheels, handles or pockets.
Measure it packed
Soft bags grow when full.
Check your fare, not just your airline
Some basic fares allow only a personal item.
The three numbers to write down first
| Measure | How | Why it matters |
|---|---|---|
| Longest side | Packed, including wheels, handles and outside pockets | Airlines measure the bag as it boards, not as it's listed |
| Middle side | Packed, across the widest point | United's 10-inch limit is the tightest published number we found |
| Shortest side | Packed, at the fullest point | Soft bags grow when full, and depth is where they grow |
A bag that measures no more than 17 × 10 × 8 inches packed fits every published personal item limit in our personal item guide.
Common questions
What size is a personal item?
It depends on the airline. American, United, JetBlue and Frontier publish limits; Delta, Southwest and Alaska say it must fit under the seat in front of you. 17 × 10 × 8 inches fits all four published limits.
Do I measure my bag empty or packed?
Packed. A soft bag that meets the limit empty can miss it once it's full.
Can a backpack be my personal item?
Yes, if it fits the airline's size limit. Several airlines name backpacks as examples. See the personal item guide.
