3.5 years for CA, over the last 10 years of the regional industry and heck, going back even further? It's awesome. But the way the industry is right now? It's pretty glacial. Horizon's upgrade very nearly went to the street. Not only that, but that is the most junior west coast base, probably in a CRJ (I don't have shiny jet syndrome, but the longer legs are certainly on the 175), and to go be the plug.
If I was a 1500 hr CFI that wanted west coast, and a quick upgrade, I'd put Horizon and Compass as my #1 and #2. Compass is obviously a bit riskier until they announce the contract renewal, but even worst case scenario, everybody will do OK in this hiring environment.
