About the B737 with different models.

Our company comprises of 800w, 900er and 800sfp and on and on the flight plan it lists the aircraft type as 73HQ/HT/JP/P. Cannot really distinguish which model we are on for flight.

What are those numbers and the the reference is always welcome!

ICAO listing, 31 different models. Your 73HQ/HT/JP/P don't get a mention.

Those look like airline internal codes, probably extensions of the IATA codes "73H" (-800) and "73J" (-900).
