Having flown Air Koryo, I can affirmatively state that they are significantly better than Spirit. No charge for checked bag, no charge for carry-on, and a free meal (the infamous Koryo Burger).

2018 strategy:
primary program: none, I will have no loyalty. Schedule, price, and opinion rules
secondary programs:
AS Mileage Plan (flying AS, rare trips on foreign partner), slightly preferred
DL Skymiles (flying DL, rare trips on foreign partners)
foreign partners on UA MileagePlus (such as SQ, LH, AC)
tertiary programs:
Southwest
4th priority, no travel, if possible
AA (biggest change from 2017 from one of my preferred airlines to avoiding, if possible)
UA itself (see partners, above)
B6
HA
at gunpoint
Spirit, Air Koryo
