First, I was to fly on the 737, this was a while ago, long ago maybe.
I had econX on the 737.
Then, it got swapped, to the dreaded 320, of course, the econX on these are over the wings and for that, they say you must be able to (while seated), lift a 25kg door and help the crew in an emergency, so I moved my seat, as I am not really able to lift the 25kg door, (tried to lift a 25kg dumbbell, hard to do while seated, lest even while standing).
So there I was, near 4 hours sat by the window, with a largish Indian lady who of course, lady spread her legs wide, into my spot, and also her husband's spot as well.
Ever since then, I have/had been hoping VA would take the 320 out of the ADL - PER route, but its looks very unlikely that it would happen.
Coming back, I think it was a F100, looking at the photos, with the 2 engines near the back, and that plane not having a rear door, out by the back, noisy as, but still, a good experience, had got a seat next to me as empty, comfort seat booking.
