听力原文：You will hear a man calling about a trip.
F：Airlines Booking office．May I help you？
M：Yes，please．I am planning a holiday in Australia this summer．Would you suggest a good airline？
F：Certainly sir. Considering your time and destination, SAS is a good choice. That is，the Scandinavian Airlines．
M：Oh？ How is it？ Are they using Boeing 757？ I like big airplanes.
F：They are doing better than that! SAS is using Boeing 767 now. It offers 2+2+2 business class
Seating, so every business class passenger is guaranteed a window or an aisle seat．And the economy seating is the best in the air, too.
M：Good. Is it nonstop？
F：Yes．
M：How about the price，then？
F：It is reasonably cheaper than other airlines. And, if you make a reservation now, you will get a 5% discount．
M：That is fine. I will think of it. Thanks a lot.
