I am trying to book a trip to France to bring my mother back home to visit. With 2 adults and 2 children it can be quite costly. Has anyone ever used the bidding option to book a flight to France? My concerns - 1. Do they really give you flights for what you bid? 2. Are they reasonable flight times? Help is greatly appreciated for someone that has only been on a plane twice in her life and both times has been close to home never over seas. Any info would be great!
