Two bag sizes, in goose terms
Gosling (personal item)
The small one. It goes under the seat in front of you and is usually free.
Goose (carry-on)
The bigger one. It goes in the overhead bin, and some airlines charge for it.
What the fit badges mean
- Honk! Fits Every side is within the airline's published limit.
- Tight squeeze It fits, but with half an inch or less to spare. Do not overstuff it.
- Grounded At least one side is over the published limit.
A badge means "fits the airline's published size limits". It is never a guarantee to board. Airlines change their rules. Always confirm size limits with your airline before you fly.
