A: I heard that you are going to the US?
B: Yes. I'm going to visit some friends.
A: I think going to the US will definitely cost you a lot. Did you make a budget for it?
B: Not yet. This is the first time I go there. Can you help me with it?
A: Of course. Let's see. First you should list all the places you are going to visit.
B: OK. My trip begins in Beijing on 1st next month. I'm going to fly to Seattle.After staying there for a week, I'll come back to Beijing.
A: Now let's budget for the airfares. I suggest you book an air ticket online now. Let's check it out. All right, I got it. A roundtrip ticket is S870 and it's a direct flight. What do you think of it?
B: Umm. It seems to be the cheapest one. OK, I'm going to book this one this afternoon.
A: Oh, another thing you should consider is the baggage fee.
B: Don't worry about it. There'll be just a suitcase. I'm sure I don't have to pay for it.
A: That's better.
