W: Fine. Is this grey suitcase yours?
M: No, it isn’t.
W: Have you got any hand luggage?
M: Only this small bag.

M: At the front of the plane.., er... Could I sit by the window?
W: Yes, of course. You don’t smoke, do you?
M: No, no. I don’t.
W: Fine... here’s your boarding card. You’re in seat E5. It’s near the front, beside a window in the ’no smoking’ area.
M: Thank you.
W: I’m afraid BA 512 is going to be a little late.
M: Is there something wrong with plane?
W: No, no, nothing like that. I’m afraid there was a lot of fog in Milan this morning, so the plane was late leaving.
M: What time are we going to leave?
W: Well, as you know, the flight is due to leave at 14:30. I think it will be 35 minutes late.
