I went to Trip Advisor to look up flights. The prices that they quote for flights on the Air Canada site are not the same when I click on the fare and then are redirected to Air Canada. There are a number of flights that have this same situation. What gives?? I don't understand that the Trip Advisor search would come up with the wrong prices on the Airlines own site. I can understand 3rd party sites being different (as they quite often are) but not when the prices quoted are directly from the airline. What gives?
