Which flight will the man take?

W: Air China has a flight on August 27th. Will that be OK, sir?
M: No, I’m afraid not. My sister is getting married on the 26th.
W: How about Air China Flight 985 on the 25th?
M: Oh, that’s good.

M: May I know your e-mail address?
W: I’ll send you an e-mail, so we don’t have to do the spelling on the phone, OK?
M: That’s a good idea.
