Have been searching the internet for a while for a good deal to New Zealand and the best deal by far is from Orbitz. The price has come up in what I reckon is US dollars, and when I used the google converter the price is great! If I book this will my credit card automatically convert this into sterling?

Has anyone used this company before to book flights. The flights which are coming up are quantas - are they ok?

Any info gratefully received!
