Anyone who has used the fiendish travel site Travelocity has seen the above 'disclaimer'.  While it is true that some of the airlines charge a fee for changing your ticket, what they don't tell you is that Travelocity charges $50 for each ticket for changing the reservation.

So, if you need to find some inexpensive travel, simply use the Travelocity search to find a cheap fare, then go to the airline website and get the exact same ticket for the exact same price.

If you should have to cancel later, you will avoid getting hit with a huge fee and keep the money away from those devils.

BTW, Southwest Airlines never charges a fee to change a ticket, and they don't list with Travelocity.  Just something to keep in mind.
