interesting, now that my bid Y-PE is accepted on the outbound, i receive a message "We were not able to find your itinerary or this trip is not eligible to request an upgrade." furthermore when attempting to change seats i receive a message "This booking can only be changed by calling our Guest Contact Centre because Travel Extras have been purchased." Does this mean the ticket is out of sync? I did receive new ticket numbers after the Y-PE upgrade processed.
I want to know if the ticket is out of sync before I get to the airport this afternoon, because I am starting my journey with DL on a separate ticket and want to be able to check my bags all the way through at my origin, which typically DL will allow.
