What are the speakers mainly talking about?

W: Excuse me. Our flight was supposed to leave 10 minutes ago. Is there a problem with the plane?
M: We apologize for the inconvenience, ma’am. Actually, the plane had some mechanical problems, but they have been solved. We promise that it’ll take off in 10 minutes.
W: Well, I hope so. I have an important convention to attend in Tokyo, and I shouldn’t be late.
M: There will be an official announcement to notify passengers about the plane’s departure. As a token of apology, we’ll give you a discount coupon that you can use on a future trip.
