Southwest bag rules worth knowing
- At 24 × 16 × 10 in, Southwest's carry-on limit is the largest of the major US airlines.
- Overweight (51–100 lb) or oversize (63–80 in) checked bags cost $75 each way, charged once if a bag is both.
How Southwest compares
Carry-on size rank: 5 of 25 (63 L); personal item: 1 of 22 (35 L).
A bag at Southwest's full carry-on size also fits the carry-on limit of Frontier, Sun Country, but is too big for American, Delta, United, Spirit and 18 more.
A maxed-out Southwest personal item is too big to be a personal item on any other airline we track.
