Here's a follow-up of what happened to my Delta booking on itn mentioned above:
ITN/AmEx/getthere called me at 8 am today. They said they could not issue me the tickets because Delta had incorrectly loaded the fares. They said they talked to Delta, and that Delta would not issue a waiver for the tix.
Then I called Delta. They said that the travel agency's delay was what caused me to not get the fare. Remember, to purchase on ITN, one enters the cc info and then clicks "purchase"--I had done this.
So, should ITN issue me the tickets anyway, as Delta has implied?
And if the issue is that the fares can change before the website issues the tickets, does that mean we have no guarantee that the price will be the same as when we clicked that "Purchase" button?
BTW, I don't see this as a $0 Hilton deal; I was paying several hundreds of dollars for these seats.
