I was looking around for some flights in September and went to my usual source which was travelocity’s flexible search option. However, it seemed to have disappeared. I did a search and found the followingarticle from smarter travel.
In essence, because international airlines have started to screw around with various add-on prices, travelocity’s flight listings did not comply with some US government department regulations. What is the solution? As far as I can see either or both of the following options

• travelocity should allows it’s non-US websites to use this feature as it does not have to adhere to this regulation
• some regulation forcing airlines to quote all-in prices

After yesterday’s events, perhaps airports in general should be avoided for a while.
