There will definitely be some animosity from some Eagle guys.
It doesn't look as if PSA-Envoy relations are ideal to say the least.
Seems to me that most pilots in other carriers including the majority of Eagle pilots get along in the real world, despite differences in opinion.

Can somebody please briefly explain to me (a non-121-airline pilot) what PSA's SAP is, how it works, and why you PSA guys like it so much? I'm genuinely trying to understand how it works.

I fixed that for you....

Every single person I've met since this all went down has been a professional, and acted as such. Regional and mainline alike.

SAP Schedule Adjustment Period.

A 24 hour period that you can:

adjust your schedule with great freedom.
Work more or less. On the days you want to or not want to.
Trade inefficient 4 day trips for efficient 3 day trips. Get more money and work less days.

Not trying to start a riot...honest question...will the SAP be around for awhile or is that a loophole that could possibly be done away with?

It'll be around. If there's a way the company can get around it then they would've implemented it last year. Don't let that be the deciding factor. I would still choose being home based over having sap. Upgrade would probably be around 5 years for the new hires right now. There are bunch of guys and gals that got on at the right time and will upgrade within 2 years of their hire date.

So how much could one expect to credit using the SAP with 13 to 14 days off per month?

I have 18 off for may with 95ish, but I think 85 with 18 is more sustainable.

If you were to add 4, or 5 critical days to your schedule you'd get 1.5x pay at 4 hours min for each day.

So assuming the 85 starting point you could be at 105-110 minimum. If the days you added were critical.

You must be including a critical day or two in there. 12 days working and getting 95hrs credit is 7.91hrs/day.
Finding 8 hour days is tough. If you had 4 days only worth 4 hours then your daily average would need to be 9.85/day to make 95hrs.

Realistically if you work 15 days in a month you will make 75hrs credit.
More if you move or shift to critical days.

What a pile if BS....PSA are the scum of the indusrty right now, and although mainline airlines outside if AAG might be clueless, the regional guys aren't. All captains I have flown with at L-EGL will all tell you to FO, if you are a PSA guy begging for a W1 ride.

I've not had a one PSA guy check in and say hi to us in the cockpit on a commute, since the YES vote....hmmmm, wonder why?
