W:(13)Could you please give me information on airfares from Miami to Bellingham, Washington?(14)We’d like to buy somehow good flight as cheaply as possible.
M: Let’s see. I want to advise you to pay the normal one-way economy class fare of $ 555.(15)If you can fly on a Tuesday or Wednesday and buy your tickets at least 21 days in advance, I suggest you book a round-trip excursion flight.
W: But we may not need the return tickets.
M: That’s all right. Even if you don’t use them, you should be able to save $ 89 over the one-way fare.(15)Of course, I’d recommend early booking. You ought to try to reserve the " Super Saver" seats. There are only a few of them and they are 50% cheaper than the others.
W: That sounds like a good idea.
M: Wait, to save another hundred dollars or so, why don’t you book a flight to Vancouver, Canada?
W: But that’s farther than where we want to go.
M: I know, but you can take a bus from Vancouver back to Bellingham and still save money. And if you are travelling with children, you might be able to get a discount if you fly economy class. But they don’t get any discount.(15)But to take the advantage of the airline’s guarantee fare policy, you’d have to make reservations and pay for your tickets at least 6 weeks in advance. Try and begin the search for available seats...
W: No, thank you.
M: Excuse me?
W: I may call you back if we don’t decide to drive.
