Some details.
The Contract was signed off by DW about 3 weeks ago, it's currently being implemented.
The reason they are still flying under the Freedom certificate is pure inertia as far as I know. It makes little economic sense to fly aircraft for the same company under 3 separate certificates. If it does, nobody I know can figure out how it does. In fact it costs Mesa Air Group a heck of a lot of money since they have to have 3 completely seperate management organizations (3 chief pilots, 3 directors of operations, 3 separate dispatches, 3 separate crew scheculers, etc..). To me and everyone I've talked to it would make a lot more sense to combine all the certificates and eliminate all that wasteful redundancy, but sense and the management of this company's management rarely go hand in hand. Of course this whole certificate issue is an FAA thing, another organization notorious for not making sense. It may be that Mesa can't fly the 700/900 on their certificate without the FAA saying 45 Ave Marias, singing 10 islamic hymns and ritually sacrificing a chicken over the paperwork first.
Right now as far as I know, none of the ALPA Mesa guys are flying under Freedom yet. It's been about a month since they began allowing ALPA folks into the 700/900 groundschool and that's probably too short a time for them to get done all the training and IOE to get on line. So probably all the pilots actually flying Freedom planes right now are still the jerks that robbed the rest of us of whatever negotiating leverage we might have had. That will change very quickly though. There will be a lot of union guys taking over the seats from Freedom in the next few months. About forty are in various stages of the transition class right now.
None of the CCAir guys are back to work yet. The only ones who've come back in are the ones starting RJ training this month. They will be coming back in spurts as the classes open up.
The callsign for Freedom is "Freedom Air". There is still a short window open where the person on the radio is pretty much guaranteed to be one of the jerks. After that, they will start getting flushed out of their comfy seats. So you can still get in a little uniformed 'tude for a little while yet if that's what floats your boat. After that window closes, save your chilly looks for the guys on the list. All the mesa guys have those lists, believe me and they are floating around everywhere else too.
