Thanks again for the information.
I "booked" my flights this morning on the website. Went through everything, hit complete purchase and I got an error message saying my request couldn't be completed and to try again or call. I tried again online and got the same message except the second time I got a message from AMEX that a large purchase had been approved and the reservation shows up under My Trips. When I go into it to choose seats it won't let me saying that tickets have not been assigned yet. Is this something that has been happening to others? If it continues I will call after work. I have also not received any emails from Delta like typical when booking.
