I have a really weird DP:
I booked an award for 2 people with Qmiles last year for a particular flight in december, and I am able to select middle seats, and using that booking reference I can still change to other middle seats.
I booked a cash ticket for 4 people recently for the exact same flight, and I am not able to select middle seats.
ExpertFlyer shows those seats as blocked, and QR call center wouldn't assign middle seats for the cash booking.
Any other insight into this because this isn't related to load at all since I am able to select middle seats still on first booking
