I tried to book a flight on Dec. 20,2016 for March 7,2017 from Sarasota FL to Montreal return in Canadian dollars. I found an acceptable flight and price of $715. I clicked on complete booking and received a pop-up that price had been reduced to $654 and asked me to complete booking at that price. I immediately clicked on complete booking at $654 and immediately a pop up announced the price had now changed to $825. This sounded completely insane. I then called customer support where I was told response time was 3 minutes. After a 20 min. Wait I hung up and called again then the recorded message said wait times were 6 minutes. I held for 30 minutes and hung up. I then called the airline direct and booked the flight for $415 US which is about $553 Canadian funds.
Questionable business practices and poor customer support saved me $272 Canadian and cost travelocity a regular customer of many years. I suggest you book directly with airline.
