Hello, I have used priceline successfully for hotels. I have never bid for airfare. My son will be traveling to Germany for a month. The cheapest price we have found is 1017 with Orbitz. I have seen lower rates, but they have not included taxes and fees. If i bid, is the bid the total price or will they add taxes and fees? Are there any suggestions on what to bid? His dates are a little flexible. thanks pam
