I’ll throw a theory into the mix for fun
UA wants to consolidate regionals. Mesa contract is ending very soon. Their contract is 30 175s and 20CRJ700s.
UA has 20 firm 175 orders to replace the CRJ700s, which will either disappear or become 550s. The 30 E175’s go to Expressjet, the carrier that UA wants to grow, especially on the 175 side. Expressjet can’t staff that.
ExpressJet (or whatever shell company) acquires compass.
As for our AA stuff, I have no idea. 2023
