Hello! I just booked my first Q suite award ticket(s) (YUL-DOH-BKK) for next year. 2 individual tickets with avios using QR privilege accounts on 2 separate accounts . I accidentally already picked my seats when booking and I was wondering are seat changes free or will I incur a fee to change them? Also I wanted to book the 2 middle seats so I believe I would have to call in to have that done since the 2 tickets are on separate PNR which is why they were blocked out, is there success in doing this?
