When I used to use Travelocity and/or Expedia to find my flights, after determining which flight I wanted I'd book it on the airline's site. The airline's site would typically be $4.50 cheaper than than Travelocity/Expedia (can't remember which one I used to predominantly use). I've always assumed that Travelocity/Expedia was marking up the flight a bit to get a piece of the action. tls
