A while back, don’t remember the route, but we were delayed after boarding for at least 45 minutes waiting on a part to repair a galley door latch. A lady in the bulkhead asked the FA if she could move to 2A. FA said she would ask the GA and a few minutes later told the lady that the GA said that seat had to go out empty. This was not a CRJ so there was no weight/balance issue. Thought that was odd at the time. I saw several pax from Y “engage” the FA about not getting an upgrade when an F seat was open.

Then this past Saturday,I was flying BA from LHR to MSY. Club World, the only premium cabin on this route, is in two sections. There were 5 empty seats out of 21 in the first section. They remained empty the entire flight. Luckily one was across the aisle from me and I snagged the extra pillow.
