The three baggage types, explained

Airlines split what you travel with into three allowances. Each has its own size and weight limit, and the one you exceed decides what you pay.

Personal item

The small bag that goes under the seat in front of you — handbag, laptop bag or small backpack. Usually free and rarely weighed.

Carry-on

The wheeled case you take into the cabin and store in the overhead bin. Sized at the gate, and weighed by many airlines.

Checked baggage

The large suitcase you hand over at the desk and collect at your destination. Charged by bag, with strict weight limits.
