M: O’Connell Travel Agency. Can I help you?
F: Yes, please. I am planning to fly to New Zealand to attend a conference next week. What I am thinking of is to stop by in both Singapore and Sydney for a short visit on my way back. Can you arrange the trip for me and tell me the cost?
M: Sure. First you can take Australian Airlines from Auckland to Sydney and stay there for no more than seven days. That will cost about $ 500. Then take Singapore Airlines to Singapore, which will be about $ 600.
F: Well, that would be too much for me. How about the ticket from London to Auckland?
M: The ticket from London to Auckland will be $ 1,200. So plus the ticket from Singapore back to London, which is about $ 500, altogether that will be $2,800.
F: Oh, no. It’s more than I can afford. Do you have any discount?
M: Well, if you’d like to take night flight to Sydney and Singapore, there will be a 50% discount.
F: Night flight? What time?
M: 11:30 at night usually. It’s about a 5-hour flight. Of course, it’s tiring, but it makes quite a difference to your money.
F: OK. That’s not a bad idea. I’ll take the 11:30 night flight. So that’s about $ 2,250 in total?
M: You are right. Can you give me your name?
F: Yes, Lynn Prescott. It’s P-R-E-S-C-0 double T.
M: And when are you planning to leave?
F: Dec. 16th.
M: I am sorry, the tickets for the 16th are all booked. How about the 17th?
F: That would be fine. And another thing is that I want the ticket valid for three months.
M: That’s no problem. Now you can pick up your ticket any time before the weekend.
F: OK, thanks a lot.
