I'm planning on flying to Germany in August for three weeks and have been trying to find cheap flights. I ran across Priceline's Name Your Price for flights which can give me a flight as low as $500. I'm wondering if anyone has used Priceline to get an International flight and if so, is it worth it? I can save over half the cost of the flight using Priceline, but I just don't know what I'm getting with those savings so I'd really appreciate if others could give me their opinions and experiences. Thank you.
