I see no problems cramming in as manny seat as possible for the cheap seats, when anyone can spend a little more for preferred seating.
I generally agree with this, however, keep in mind that on the ACr 319 there are precisely two preferred seats where tall people comfortably fit (19A and 19F). Your point is valid and well-taken on the 763s and to a lesser degree the 321s, but the 319s are a real problem even for people willing to spend money on preferred seats.
Back to Calin’s salary, well, good for him.
