I am on an A321 (I think CEO not NEO, it just says A321).

My wife is in 2A, I was moved from 2B to 1D (separate PNRs). The cabin is full, the flight is next week.

If thought, 1D is the worst seat in the First Cabin. I have a bad knee and can't fly that long without the legroom. Or is there plenty of room? The agent said that's where they put folks with a fused leg.

Delta Comfort is full except for a middle bulkhead. The other flight times are no good (leaving at 7am, or arriving after 11pm). Other than setting alerts in EF, I"m guessing I'm SOL? Any recourse to get them to move me back?

I see why I might get moved out of a bulkhead but why did I get moved to a bulkhead?

ETA - I was told I was "moved by the system" to accomodate a family - but it doesn't really make sense. They said if I cross referenced my resrevations, it wouldn't have happened. Lesson learned.
They say only the gate can move the seats now.
