The SAP is the greatest quality of life tool at the regional level. It has been said many times, and is still true.
PSA is not all unicorns and rainbows. Not at all. But, if all you want to do is to go to work, fly a good schedule, get paid pretty good money to do so, and go home - it is pretty darn good.
My wife and I have a trip planned for February. Tickets are purchased (I bought tickets - 20% off through AA so I don't have to worry about non-rev), non-refundable hotel reservations have been made. We even have a couple tours planned. I do not have a vacation in February, and I am not worried in the least about getting those 8 days off. I know I will be able to SAP and get the time off.
