On what day will they meet? How did the man send the parcel finally?

M: Look, Lynn, I think I have to make our meeting on 18th of October to another day. You see, I have to go out to our branch office in Los Angles to attend the opening ceremony.
F: Em, yes, let me have a look. Mm... How about 21st?
M: 21st... Oh, I have an appointment with my lawyer on that day. Is 22nd OK?
F: No problem. I’ll write it down.

M: How long will it take for a parcel to get to New York by air?
F: About a week.
M: Then how about by ship?
F: Well, that would be much longer, about 40 days.
M: Well, I’ll send it by air then.
