What is the disadvantage of an excursion fare? [originaltext]W: Good morning. Ca

W: Good morning. Can I help you sir?
M: Yes, good morning. Er, my name is Adams. I am going to a conference in Sydney in July.
W: Yes. How long for?
M: I expect to be there for about three weeks.
W: I see. Well, there is an excursion fare.
M: How much would that be?
W: 795 pounds. That allows you one stopover, one stopover outside Australia.
M: Only one stopover?
W: Yes, [7B] that’s a restriction on excursion fares, one stopover and not in Australia.
M: I see. Well, I suppose it would be nice to have a stopover in the far east somewhere, Hong Kong or Bangkok. Hm. And there’s another point. Er, I’m going with two friends and we have got a friend in Perth in Australia. Now we all know him and it would be very nice to visit him on the way back to London after the conference.
W: Sorry sir. [8C] You’ve got to remember, no stopover in Australia on the excursion fare. Of course, you could pay the full fare.
M: Mm. No, I don’t really want that.
W: Or, well, there is something else you can do. You could take a single ticket to Sydney, that’s 400 pounds, [9B]and a ticket from Sydney to Perth, about 150 pounds, and then another single Perth to London, that’s about 420. That’s much less than the full fare. But remember, no stopovers allowed on single flights, so you wouldn’t be able to go to Bangkok or Hong Kong.
M: I see. Well, I’d just fly directly back to Lodon. But look, if you don’t mind [10D]I think I’ll talk it over with my friends first and I’ll come back in a few days time. Um, I hope they’ll come to Perth with me. I’d really like to see my friends. Anyway, um, I’ll see you later.
W: That’s fine. I’ll see you next week perhaps. Goodbye.
M: Bye.
