Which airline ticket websites for international are the cheapest?
No website is always the cheapest on every route on every day. Taxes will be the same on every website. Those are set by the respective governments and websites have no control over them. $1400 is a lot of money for this route unless you are traveling very soon and missed the advance purchase requirements for the cheapest fares. Or, if you are traveling over the holidays and the cheap seats are sold out. If either of those are the case, looking at more websites probably will not do you any good. Other than ticket consolidators, fares and seat availability are set by the airlines, not individual websites. I had no difficulty finding a fare of well under $700 for Dulles to Geneva in mid-January. Try Kayak.com. It shops many different websites and combines the answers. You can easily try different dates and see if the fare changes. They can’t guarantee the lowest price, but they do save a lot of time shopping.
