Maybe I am incorrect, but I thought DOT did consider coverage? Isn’t this why it’s much easier to drop trips during MOT v DOT?
I certainly do understand that there won’t be as many conflicts generated with PBS. This is true. PBS avoids conflicts.
Regarding the 4%: is the four percent not what is referred to as unstacking? If anything in open time greater than the four percent will be placed on pilots schedules without respecting a pilots selections, is this not what we should be concerned about?
And vacation? Don’t try to fool us with that one. PBS reduces our current vacation and reduces the number of days off compared to what we can currently generate with line bidding.
Why in the world are we even considering a TA based on PBS? For what? The union keeps telling me that I’m going to keep my schedule flexibility, but now I’ll be awarded trips that I haven’t bid for? PBS, as efficient as it is, will also drive some bottom line holders to reserve. It will be all that they can hold.

The reason it is SOMETIMES easier to drop in MOT is that the DDLs are higher, however that doesn’t guarantee you can drop a trip. (ie it is typically easier to drop a Christmas Eve or Christmas trip because relief lines clear out most of the open time that’s left after monthly.
The 4% open time limit allows the solver to leave more time open after the build. It can build more lines if there is flying that pilots want, but won’t if it isn’t. In the current book we are left with approximately 1% open time at the start of DOT, so with a higher limit pilots are less likely to have flying added to their schedule that they don’t want. At some point flying must be added to pilots schedule, this is true in line building and pbs, we can’t have 100% of all flying left in open time after the build, so some pilots preferences won’t be honored. That is also true today. Someone has to work weekends, Christmas, etc.
As far as vacation, I’m not trying to fool you at all, with vacation being worth 5:00 of CREDIT(not; pay no credit) you will absolutely be able to net the same days off, long blocks off as you do under line building. Junior pilot’s will likely do better under pbs with the inviolate days allowing larger blocks of days off.
The association said they ultimately considered PBS cause the company wanted it so bad they, 1) agreed to the best vendor, 2) a pbs letter that assures is of great language like DL, B6, HA and NK have and most importantly 3) industry leading value of vacation with current book for drop/swap which allows us to modify our schedules after DOT opens.

This has been explained multiple times in these threads and yet you either do not understand or just refuse to believe it.

Pilots love to complain about unstacking in PBS. Keep in mind regular line bidding is 100% unstacked. They do not leave trips on holidays and weekends in open time. They are all built into the lines. PBS on the other hand can and usually is programmed to allow some stacks to develope over holidays and even weekends. How big or little the stacks run is determined by the negotiated work rules. Very few airlines with PBS have 100% unstacking.

Line bidding is 100% unstacked. True because you are bidding on the final product. You are able to bid on the post process using your seniority. So no matter if the lines were adjusted to accommodate extra coverage on certain days has already been done prior to bidding. The pilot group then gets to bid with seniority for the good vs crappy lines created due to whatever process the company used. With PBS your seniority means squat when you get unstacked. It is a stack created DURING the bidding process WITH PBS. You don't have a choice when you get unstacked with PBS. Do some research on unstacking before claiming we have it worse now with 100 percent unstack vs PBS unstacking. Geez.
With the unstacking limits we will likely get, unstacking will stop at the 50% seniority mark on holidays and 30% up the list on normal days.
The reason you saw the levels of unstacking you did at Mesa was because of the massive staffing shortage and virtually unconstrained (contractual) line values that the company could set in the software. This meant many of the junior pilots became FAR-illegal to accept any more flying on their schedules, forcing stacks higher up the seniority list. I doubt Frontier would let it get anywhere close to that bad on the staffing front here.
Additionally, since crew planning was the one running the software at Mesa, they had a “good enough” approach to running the solution and didn’t care to try multiple iterations, tweaking parameters to reduce the overall level of unstacking (although I think in many cases they did with input from ALPA). In our case here, ALPA will be the ones doing the tweaking and playing with the solutions until they can get an optimized solution that benefits the group as a whole.
If anyone wants to read the Delta PBS guide, it explains it a lot better than I can:

In the area of unstacking (coverage awards as Navtech calls it), Navtech respects both seniority and pilot preferences at a much higher level than other software.

No matter what system you use the exact same number of pilots need to work holidays and weekends.

I gather you have not bid under a modern well executed PBS system. You can easily avoid unstacking via negative preferences and defaulting to a reserve line. Pretty much exactly what you do with paper line biding. Unstacking was held out as a giant bogeyman at my airline before implementation of PBS. Now you almost never hear about it. The vast majority of pilots would not return to line bidding after using PBS. I suspect the margin would be 95% for pbs at my airline. You will almost never find that level of agreement amongst pilots.

Spirit has yet to agree on unstacking limits. From the sound of it they will likely be testing the arbitration language for this within the next month or 2. Rest assured that whatever they’re awarded, Frontier will not agree to less. Likely an arbitrator would not make Frontier’s less favorable either.

I am not sure what ALPA has to do with SWA. I can tell you that in contract surveys a return to line bidding is requested at a rate under 1%. SWA is extremely efficient in pilot utilization. Far more so than any legacy. I doubt PBS was a high management priority at SWA. PBS at Delta came about in LOA 46 not the bankruptcy contract. PBS can reduce your overall pilot manning depending on the work rules. That is why managements push for it. Delta has PBS however their overall work rules require more pilots per airframe than SWA.
