Where is the talk taking place?

W: Good morning. This is the East China Airlines.
M: Good morning. I wanted a seat on the 11 o’clock flight to Lon don next Saturday morning.
W: I’m sorry, sir. It’s fully booked.
M: Oh, would you fix me up with another flight on Saturday?
W: Well, yes, there is a flight leaving at ten o’clock on Satur day, but you would have to stop at Sharjah for about one hour in transit (中转).
M: Ok, that’s fine. Thank you.
