Thanks for the quick reply. United.com didn't show theirs, but I found the same flights on Expedia and they show about $80. It's strange that American's 1 stop flights show only $53 in taxes and fees, but their total cost is still higher than United's. We're adding either a day before or a day after our originally planned dates (if we were to buy tickets elsewhere) for flexibility and re-bidding, I just don't want us to spend 16-18 hours traveling. If we can get the tickets for $500 or less, I'm thinking we'd be saving at least $350. Do you know which airlines issue paper tickets as opposed to e-tickets? Does it generally buy the tickets from the lowest priced airline that it shows you before you put in your final bid price? I played with a couple different scenarios on Priceline this morning after I saw a ticket delivery fee: Depart 9/2, return 9/10, paper tickets. Lowest priced airline United. Depart 9/3, return 9/10 or 9/11, e-tickets. Lowest priced airline American. I really appreciate your help.
