Maybe not, but many airlines do and this should be the standard that other airlines should be shooting for in negotiations.
Well sure. And twinkies with every crew meal. And nobody has to work on Wednesdays.
Everything has a price tag (which adds up surprisingly quickly) and needs to be prioritized. Something that mostly only effects half the pilot group (FOs) might not rank as high as something that effects all of the pilot group (wages and work rules). It's great if you can get it, but when resources (money the company is willing to spend) are limited, you have to decide what makes the most sense.
Quick history of the PSA displacement language...
Prior to 2013 there was no displacement language. The company would, each month designate certain checkairman who's awarded lines (no PBS) would be blocked from FO bidding. There was no restriction on this number although there was some vague language about the checkairman flying having to be spread "evenly" between the domiciles. The problem was that, often times, checkairmen were senior and had the good schedules and as such FOs weren't allowed to get those schedules. There was one year where there were NO FO lines with Christmas Eve/Day off in one domicile because all 5 lines that had it went to checkairmen. Then, invariably, there wouldn't be enough new hires or upgrades who needed flying (line checks were normally done from the jumpseat) and reserves would have to come in and fly with the checkairman all the time.
Pilots (well, FOs) hated that they were blocked from bidding good lines and the company didn't like the fact they were constantly burning reserve FO to cover the flying. However, we discovered that, despite them not liking the reserve utilization, they didn't dislike it enough to throw any money at the problem. Margins at regionals, even WOs are pretty damn tight and instead of us using negotiating capital to solve a problem that only effected FOs (and not all FOs at that), we decided to save that money for pay rates (and a min day, which was the single biggest win after SAP in that contract) and make a somewhat cost neutral solution that solved the issues pilots were complaining about.
So, you can be displaced ONLY if they call you before noon the day prior to your report time. This solves the problem where a guy commutes in, is told he's displaced 30 minutes prior to starting and now has to pay for a hotel because he can't get back home that day.
If displaced you have to be reassigned flying at the time of displacement and it can't start earlier than your original show time. This way guys won't have to commute in any earlier than they were planning to. Likewise the trip can't exceed the original footprint or extension rules and pay apply.
If there is no trip they go to long call and are still protected by the original footprint of the trip.
Paid the greater of the trip they were displaced off of or what they fly.
So yes, a guy who is displaced doesn't get free days off, but they won't end up working any more or on any days they weren't planning on working already. They have the ability to make more (not double pay like some places do have, but at least the greater of). It's not perfect, but it was a huge improvement that cost almost no bargaining capital, which in negotiations, especially at the regional level, is a big win.
