Except a WO pays more than your options with a guaranteed flow to AA. I dont know what better long term pay you could ask for than a legacy airline. PDT has quick upgrades, great pay, and a growing fleet but no E170s. Our turboprop FOs out earn Mesa Captains. You pick what matters more to you. Personally, i'd think hose ERAU loans are gonna be hard to pay off making 22k a year at Mesa.

You need to spend some time reading on this site about the various work rules and pay at each airline, as well as the number of people who can't get a call from a major despite all their glorious wing mounted engine time. Aircraft type should be one of your least concerns versus pay and a path to a legacy. Mesa shouldn't even be considered as an option at all.

If you REALLY must have an E170 that bad, go to Envoy.
