I just did a trial run on Hotwire, much to my dissatisfaction. It was for a r/t FLL to PHL. US had it for $175.00 and it's not Metro Jet. That's cheap! Hotwire will sell it for $155.00. It's not worth $20.00 to commit to a fare when you don't know the time you are leaving or returning and whether or not you are going to make a stop or change enroute. I think even most leisure flyers would be afraid to buy "in the dark" let alone someone with a schedule to stick with. If one could see the itinerary this would be a great site. Until they incorporate schedule information this site will only be suitable for the most hard up of flyers.
