CDG-EZE award flight changed from evening departure 787 to morning departure A350. This was a few weeks ago, received email about schedule change and accepted the new flight.

Now for two weeks Delta can not figure out details of the new flight.

• Android app shows old schedule (evening 787) and the seat selection does not work.
• Delta website shows correct morning departure, but old equipment 787. The seatmap in on the website however shows correct aircraft and seatmap for 350.
• When I tried to book a new flight because I needed to change date, both app and website showed correct time and equipment, but right after booking there was a schedule change notice, which I accepted and it resulted in exactly the same mess.

Edited to add: Called Diamond line, they were just as clueless. After some time on hold while they were investigating, they suggested to call Air France, because they could not figure it out..Representative said their systems also had conflicting information and they were not sure what was real departure time. Amazing .
