Actually, using Priceline for an overseas flight makes a great deal of sense, and I'll explain why. Being that I live on the east coast, except for the few flights that both BA and American Airlines have that depart the US in the morning to London, which arrive in London in the evening, all other flights to Europe departing from the east coast depart in the late afternoon or evening, and arrive in Europe in the morning. Except for not knowing the airline, and that Priceline does not tell you in advance that you might have to make a connection (it most likely would be in North America), you would basically arrive in Europe only within a couple of hours of your intended arrival time had you booked a flight knowing the airline and the departure time.<BR><BR>As an example, I am flying to London the day before Thanksgiving. Normally, I would depart either at 6pm or 8pm on BA, Virgin or American and arrive in the UK at 5 or 7am. Presently that flight would cost me approximately $400-$500 plus $100 in taxes (the fare was $500 6 weeks ago when I made my decision to go to London). Instead, I depart at 4pm via Toronto on Air Canada, and arrive in London at 5am, and the total cost of the ticket is $279. Now, I lose out on the frequent flyer points, but I save myself between $200 and $300, which is worth much more than the frequent flyer points. On the the return flight, I depart at 1pm, instead of 10am (the flight I usually depart on from London), and I arrive back in Boston at 5pm instead of 1pm. Leaving a bit later from London, I get to stay out a bit later the night before. I think this is a win-win situation.<BR><BR>After my bid was accepted, I immediately called Air Canada to see if my reservation was in its system -- it was, and I was able to get a seat assignment.<BR><BR>Priceline is not for everyone, and its not a viable option in all situations. For flights within the US, you might not win your preferred departure times, but for Europe, it logically makes sense. <BR><BR>For hotels, if you use Bidding for Travel as a resource, you do your research, rely on the information provided by other winning bidders, as an educated traveler, you'll end up with a hotel at an exceptional value. Bidding for Travel also has a section on its site where travelers review the hotels, which is no different than the information that we share here at Fodors. I've been very lucky with hotels, as I've paid no more than 40% of the best rate the hotel had to offer for my scheduled dates.<BR><BR>I for one was very leery about Priceline, but I've had a lot of success with it, and will continue to use its services when I can.
