Hi...Just a note from experience. Priceline.com If you know that you will go on your trip, with very little chance of changing or canceling your trip(but they do have a $25 fee or so for insurance in case you have to change your date for emergency of some kind), then try them first. I had gotten a ticket, for the whole month of Sept. of this year, for $450 roundtrip before taxes ($513.00 total), and Sept.is high season there in Spain. I had looked at the lowest price from many sites, which at that time was $832 with some European airfare site. But still, it was too high for me, so I thought, what was the lowest price that I had found in the off-season, and remembered about $500, so I tried $450 and within 5 mins, Delta accepted, and it was cool. So my advice, try your lowest price, and work from there. I think you are allowed one or a certain amount of bids a day, so read the fine print. Good Luck-
