FO's probably 45 dfw / 45 iad, the key here is no 700/900 pay diff. There will be far fewer FO's to shuffle due to upgrades and people that already transferred to keep a line. Wouldn't be surprised if FO displacements are deferred for several months due to upgrades / quits / and the out of balance FO / CA #.
CA's probably 70 dfw / 45 iAd, 700/900 pay diff will force some to dfw to prevent pay cut.
Go to PSA if Mesa<1-2 years and want/ need east coast/clt operation. Cut losses, much better contract/ health insurance is no comparison. Mesa /JO always finds a way to screw opportunity up, it won't be long now.
