Hi, I was due to be flying from DOH to SIN on the A350, and I'd selected one of the single window seats in J. A few days ago I learned of an equipment change, to the A330, and the seat map now shows me in the equivalent seat in terms of seat/row number, but the seat next to me is occupied. As the seating configuration has changed, does anyone know from experience if Qatar would block seats or it's a case of someone now sitting next to me? There are still pairs of empty seats in J class, so I can't imagine that someone would select a seat next to someone else if there are empty pairs elsewhere? Thanks.
