Was that Flightfox? If so, I loved using it, helped me save so much money but also time :)

It sounds like there’s a problem with having too many flights that are barely full and hence unprofitable. AFAIK the federal gov spends significant money subsidising many “small airport” routes even if they’re barely used.

That’s just the nature of the beast. Airlines have to align large capital intensive assets with fluctuating passenger demand and fuel prices. And at congested airports the slots are also expensive assets that get auctioned off, and operate on a use it or lose it basis.

Spirit and the other LCC’s problem is that the legacy airlines are now offering a similar product in their basic economy that has less hassle, higher frequency, is sometimes eligible for earnings on their massive loyalty programs, etc.

The EAS Program (Essential Air Services) is the US Government program which subsidizes routes to small communities of you're curious.
