Your lucky they let you use the ticket at all. I was not so lucky with a ticket for my wife on DL. It looks like they are going to bamboozle us out of the whole fare.

We booked a flight to Europe based on when a Congressional staffer had told us the INS would untangle a snafu concerning her immigration status. Thanks to delays resulting from 9/11 changes, that time was extended way beyond the flight date. I asked DL if they could extend the time to use the ticket credit, and they agreed, telling us we had until December 2003 to use it. I booked flights for Thanksgiving to Europe to use it. Because I had left my info with the e-ticket number sitting at home, I called DL while on the road to get the number before getting to the airport, but was told that travel had to be complete by a date in October instead of December. I was rather disconcerted to hear that but began to brainstorm on how we could use the credit for a long weekend trip before the new October deadline. I decided to first call back and see if there was any possibility of another extension. The new person I got at DL told me she would check.
She came back and told me we did not need one because the use-by date was the original date I had first been given in December (I had never given her that date in the conversation. She had gleaned it from DL's record). I went to the airport to buy the ticket, but when the agent called the DL office, she was told that the ticket had to be used for travel by a date in July and that it was no longer good for anything since that date had passed.

Incompetence seems to be instiutionalized at DL when four different people can give you three different use-by dates, and the customer ends up flim-flammed out of his money. I have contemplated trying to pop them for treble damages and attorney fees under North Carolina's Unfair and Deceptive Business Practices Act. Someone needs to get these con artists a lesson.
