We booked this flight before Christmas and at the time the business class seating configuration was the old premium economy style 2 x 2 setup with 1 seat blocked off, so we weren’t going to be seated next to each other anyway. It was a phone booking and these were the seats allocated to us.
When I rang a few weeks ago to select my seats on a different booking I had made before the Sabre upgrade, I enquired about this flight. Not only could they not tell me whether the plane had been upgraded, but they also couldn’t access the seat plan for business to check the configuration or to see what seats were booked or available. Suggested I try again in a week’s time but I haven’t had chance to ring back. It also doesn’t allow me to change my seats online. I might try and give them a call again,or failing this wait until check-in is open and try then.
