I somehow didn't realize the CV-880 was powered by GE engines, but that's obviously the one (the four airlines, for the record, being AS, DL, NE, and TW). Only TW fits the JFK-ORD-DEN route, so let's try this:

BDA-JFK, BA, V10, RR
JFK-ORD, TW, B3J, PW
ORD-DEN, TW, 880, GE

I'm starting to feel like the "What's My Line?" panel when John just flipped all the cards because they weren't anywhere close to getting the guest's occupation in the number of guesses they were allowed. Thank goodness we don't have a limit here!
