Right now, all the current MDA F/O's (from the APL) have been pay protected, as they could hold a CA position, yet the the severe shortage of FO's requires them to remain in the right seat for now.
All the Classes in July, starting with mine on the 5th, are for FO positions ONLY, to make up for the shortage. After July, the classes will again be split 6CA/6FO for 5 classes in Aug. Now that they have the process worked out you should get notice of your upcoming class date soon.
NO CEL (W/O) pilot can take a CA positon at MDA until all APL pilots have either accepted or declined a CA positon first. Then and only then will the CEL pilots be selected in senority order for CA posiitons.
The easiest way to think about this is to imagine one huge list, with current Mainline pilots in senority order, furloughed mainline pilots in order after them, and then all of the Wholly owned pilots from ALG/PDT/PSA in date of hire order after them...
Since every APL pilot, is above every W/O pilot in the bidding order for any MDA position, those APL pilots still interested in a MDA Capt spot will have first crack. MDA is the "transition" between our two lists (mainline vs. W/O), in which when we come onto "your" property (MDA/Mainlne), we come in behind you.
Oh, and 320 Pilot, thank you for your words.
