re: How is everyone getting to LA since MSY Will likely be out of power?

Also, OP. Spirit is one of te worst airlines for IRROPS as they usually only fly one frequency a day. I'd look at BTR on AA or UA or try and get to houston. With days worth of cancelled flights from bot BTR and MSY they ave tons of people all trying to get out of the area.

LFT may be an option as well unless you want to stay on Spirit.
