After Checked in - my seats are changed. (no aircraft swap)
I checked my bags and got my boarding pass at City Airport Terminal 630AM in Seoul. I am flying ICN-PEK(Asiana Airline - Departing 305PM) and PEK-IAD(UA808) IAD-BOS(UA352).
My boarding pass shows 16L (UA808) and 7F(UA352). Both bulkhead seats I like.
When I came home, I checked the flight status. I realized my seats not occupied on the seat map. It turns out I was moved to different seats. I can not change it back online
I called United. The agent said. she can see my original seat assignment on UA system. However, she does not know how and why my seats were changed.
My friend (no status) travelling with me (different PNR) still has 16J and 7A seats from my status.
I need some advice. It is a 13hr flight. I really want my bulkhead seat back.
