Commutair is non-union, but there are those in the company that are pushing for ALPA. Don't know how far along they are on that front, but last I heard (within ten days) they haven't gotten enough cards to put it to a vote.
As for SA, we're Teamsters. Pay scale starts at $22/hr first year with a 72hr guarantee. 10 days guar. off on reserve, 12 days guar. for lineholders, though most lines these days have 13 or 14 minimum, up to about 16 days off. Per diem $1.35/hr for overnights only, but I'm guessing 75% of the trips have at least one overnight (some sked trips are as long as four days). Bases in Ft. Wayne, IN... Pitt... And Trenton, NJ.
I don't know the current minimums, but if you look on the website I'm told its' there. Prior 121 or 135 experience, turboprop/turbine time, and/or prior Saab experience are major pluses.
