Airline (298 words) |
 | An airline is a civilian organisation providing air transport services to fare-paying passengers and/or cargo. |
 | Where an airline has established an engineering base at an airport then there may be considerable economic advantages in using that same airport as a preferred focus (or "hub") for its scheduled flights. |
 | Each operator of a scheduled or charter flight uses a distinct airline call sign when communicating with airports or air traffic control centres. |
