Which site has the cheapest tickets, when is the best time to buy (i.e. how far out, what day etc.) and any deals that are to be had. I swear, anytime I look for a first class ticket to London it is north of $6k but when I had my travel agent book for me before she got them for $2,300 each. I know the response here is, "then why not let her book the tickets" but at his point I don't need help on the whole trip and would cut her out of the deal on a place I have already been. Unless, they get better deals or something. Palumboism, or any of you other world travelers, got any hints? Thanks.
