The city of Long Beach won't have jetBlue to kick around anymore. Maybe the city will learn its lesson and treat its remaining airlines better. Nah, who am I kidding...
I hope jetBlue can inject some fare competition into Southwest's monopoly on LAX-OAK service. In recent years LAX-OAK fares have been higher than LAX-SJC and LAX-SFO fares. The latter routes had competitors, primarily Alaska Airlines.
I doubt they’ll be back in OAK anytime soon. AS or UA probably would have been candidates to try LAX-OAK in the alternate non-pandemic timeline, but now it’ll probably just be WN (and NK) for the foreseeable future.
