I am using points only. I have twice the required points. I am doing an open jaw. The second flight is from Singapore to Los Angeles. I could purchase the tickets directly from Delta. However since I accumulated all these points I would like to use them now.
During the booking process there is an option to pay in cash or use points the software automatically defaults to points if there are enough points in the account or cash and points if there are not enough points in the account.
CSR has mentioned that this error occurs periodically and all the can do is file a trouble ticket.
I have booked a couple of times in the past when UR was handling the software and never had any problems.
