Plane<br>The man got on the plane. He sat down next to the window. Someone said that he was in their seat. The man checked his ticket. The man moved to his correct seat.
The man was on a flight that day.
He got on a plane with a ticket, clearly he was on a flight. It's difficult because "flight" is never mentioned in the text.
