I really need one of those
There must be something I'm not getting here ?
I've got a B class ticket which then upgrades into U class on a NW flight as far as I understand?
Doing a search for my NW 040 flight for the 20th of August this year on Expertflyer tells me that there are U9 tickets left.
Calling the Flying Blue helpdesk they do a search on NW and report back no availability? How is that possible? Is there any chance for me to get this upgrade through or some strange trick I just don't know ?
