They would do it for two reasons. One if they lived in Houston or maybe Austin, and two, because the CLT to DFW commute is going to be saturated with the massive closure of the CLT base. Remember there is about 300 pilots that are going to be going to either IAD or CLT. By going over to the EJet, they have less competition to CLT and way more seniority. Like within the top 25-30 on the EJet list. I am a Captain, and I have already heard of a few Captains wanting to downgrade to move the the EJet.
Unless Mesa issues one Massive Displacement covering until June with class dates that far out, Mesa has no way to circumvent the contract allowing people to downgrade. That is and has always been an option. Mesa has never issued a Displacement that far out. They can't plan farther then next month so downgrades are very possible. This will be my 5th time getting displaced so I have it pretty well covered with all the rules and little tricks and its only fair to share with others since were all in this together. Upward and Onward!
