I will tell you DO NOT use travelocity!!! I used them many times...but the trip I took in Oct was just horrible...
I got the confirmation page and email (make sure you save these - they could be useful later) and my price was $202 each...this was after I bought the tickets...on my credit card statement...they charge me $350 each!!!! WTF...they had the nerve to tell me that Delta raised their price from the time I looked at the fare to the time I clicked OK...that is bogus...THEY were the ones that missed the fare!!!
I had to battle with AMEX (actually they were very helpful) to get the charges reversed...
ETS: moral of the story: use these websites to look for fares...but call the airline directly to book
