Script:
M The airfares to Australia are quite expensive, and I know you need to economize. Let me see what I can do to get you a better airfare.
W I′ll really need a substantial discount to make my trip possible.
M I understand your situation. Now, if you are willing to change your destination and fly into Melbourne rather than Sydney, that would save you some money. And if you extend your trip by just two days, I think I can work out a really good fare for you.
W Fine, fine. The only important thing is that I need to arrive by next Sunday.
