I will be flying EWR-LHR in UC in two weeks. I am able to go through the entire seat selection process, including the final message that my seat selection has been saved.
Yet, when I go back to check the seat selection, the box stays blank. I tried this with several seats and several times, but same outcome. The return shows the seat I picked, but not outbound.
It did show the seat I picked first for a couple of days (18K), but has been blank ever since and 18K continued to be available. Now looks like 18K has been claimed
. I called and they said they see me in 15, but I don't that.
Anyone know why this is happening and how I can resolve this?
