I'm inclined to think it is not so much bait and switch as it is just the nature of the beasts. For example, last month I priced a round trip LAX-ATL on Continental's web site for $209.50 and by the time I had filled in all the necessry information and attempted to purchase, the fare had increased to $674.00! I immediately jumped to Travelocity and Expedia and it was still $209.50 on their sites. I again attempted CO and no deal, still $674. The 1,000 mile online purchase bonus on CO's site wasn't worth $464.50. I purchased through Travelocity. Within a couple hours, after purchasing for $209.50, both Expedia and Travelocity showed $674 for that itinerary.
