Passengers board an aircraft that leaves the ground, travels through the air, and lands at another airport. That journey is a flight. It is the dominant method of long-distance passenger travel.

Flights are identified by airline code and number. Duration ranges from under an hour to intercontinental journeys lasting more than half a day. Cabin classes, seat maps, and onboard service levels vary by airline and fare. Safety procedures and crew training are standardized to a high degree across the industry.

Punctuality depends on weather, air-traffic control, technical issues, and turnaround efficiency. For travelers the flight is both a means of access and an experience shaped by comfort, crowding, and delay. The moment of takeoff still marks a clear psychological boundary between origin and destination.
