What does checked luggage mean?
Checked luggage refers to luggage that you drop off before your flight at the check-in counter or at special baggage drop points of your airline. These suitcases are transported in the aircraft's cargo hold and are not accessible to you during the flight. You collect them after landing at the baggage carousel in your destination airport.
