Since I never book these things online, I tested the OP's itinerary. No where did Travelocity come back and say why the price showing was higher than the price originally shown. When we book in the GDS, we get a message that a fare is higher and we can see why with the booking class. This is the danger of booking online. You don't know what you are seeing, what is being booked. In other words, you don't have a clue to what you are booking and getting. Now I didn't go through with the final needed personal information, but the price I was looking at and what was quoted went higher with no reference to why. My guess has to do with taxes, but sine hotel and air taxes would be mixed together it is impossible for me to figure this out. My vendors break this out for me, but you don't get this online.
