. I booked flights tonight with my wife's new DL account. I was not able to put my DL FF number in and it kept giving me an error saying that "Name does not match number". I gave up and completed the reservation and then figured I would call and add it. Before calling I tried to add it within the reservation and presto it worked. I am guessing that for the name I had to use First Name "space" Middle Inital , but not sure.
