My last year experience with Skyauction.com was fantastic: saved a lot of money on international trips, traveled on the dates I wanted, flew on the airline of my choice, and got the miles. The only regret was that they did not allow an open jaw itinerary.
This year I give them thumbs down: I don't see any great deals anymore. For the price of the final bids I can easily buy the ticket from the airlines directly, especially if I snoop around their internet sites for specials. Could it be that too many people have discovered the site? Or can it be that SkyAuction people are bidding on the deals too, to keep the prices artificially high?
I'll keep an eye on SkyAuction for a while. May be the good deals will come back!
