Check Baggage SizeEvery airline allowance splits into three, checked in this order:
The small bag that goes under the seat in front of you — almost always free, and rarely weighed.
The wheeled case stowed in the overhead bin — the allowance airlines enforce most strictly, and where budget carriers differ most.
The suitcase you hand over at check-in — sized and weighed against the allowance included with your fare.
