Hoping people can enlighten me here. Booked on a 77W LHR to LAS on Friday on a discounted J ticket. Seat map exactly matches the premium heavy 77H configuration on Aerolopa. Today all of the first two rows of seats opened up 48hr before departure, and I was able to select a seat in Row 2. Am I right to conclude BA didn’t sell F on this route for some reason, and now I have lucked into a first class seat?!
