I'm no industry expert, but I don't think the F9 merger is in the cards.

They are solidly a ULCC. No premium seating options, no wifi, wait 20 minutes for a "gate" which may or may not be airstairs.

NK has invested a lot on premium options and trying to improve the overall pax experience. Maybe it's pure luck but in FLL my gate is usually open, rampers are in place, and a gate agent is ready to connect the jetbridge. This place is unrecognizable from 4 years ago.
