Common exclusions
The airport's common rule covers bags up to 90 cm in length. Oversized or special items and animals should go to a staffed airline counter. Bags with long straps or very light weight may need a handling tray.
Airline-specific limits can also affect travellers with infants, pets, special sports equipment, excess baggage charges, connecting journeys or wheelchair assistance.
Before travel
Check your terminal and airline in the airport's official T1/T2 counter table. For example, the T1 T'way C-counter lists 05:00–20:00 (up to one hour before departure); T2 Korean Air B-counter lists service from 05:00 until one hour before the final flight. Other carriers differ.
If self bag drop is unsuitable, ask the staffed check-in desk; it does not mean you are barred from the flight.
