So if it's identified as a 737-800 it's not a ship with PTV?
If the aircraft code is 738, then it's a regular old 738 with no PTVs.
If it's 73H, then it's a reconfigured 738 with PTVs.
If it's 73W, then it's the new 737-700s with PTVs.
Unfortunately, there is no way to tell in advance from the seatmaps anymore as non-AVOD 738s now also have the same 16F/144Y configuration as the AVOD-wingletted-737-800s.
