For the constrained group affected by unstacking, is there a way for these pilots to preference unstacked pairings? Or will Smartpref assign pairings as it desires?
Under Prefbid, the pilot group may not know EXACTLY where the system will need to invoke unstacking (though ALPA does recommend that the most junior pilots submit an unstack bid), but it is not a big issue to preference pairings around expected unstacking days (e.g., holidays).
For example, Prefbid might need to unstack around Christmas. Now, depending on how senior pilots bid, the unstack might be for Christmas pairings only, or it might affect pairings that fall a day or two on either side of Christmas. The unknown does not affect my bid, as I preference all potential pairings:
Unstack Pref 1: Pairings departing Dec 27
Unstack Pref 2: Pairings departing Dec 26
Unstack Pref 3: Pairings finishing Dec 23
Unstack Pref 4: Pairings finishing Dec 24
Unstack Pref 5: Pairings departing Dec 25 after 1200
Unstack Pref 6: Pairings finishing Dec 25 before 1200
Unstack Pref 7: Pairings departing Dec 25
Unstack Pref 8: Pairings finishing Dec 25
Unstack Pref 9: Pairings departing Dec 24
Unstack Pref 10: Pairings departing Dec 23
Unstack Pref 11: Pairings departing Dec 22
etc.
Using the preview window, I then can confirm that I have bid all the appropriate pairings. If unstacking is required, a list of affected pairings is generated. If I happen to be a pilot affected by unstacking, Prefbid will start at the top of my unstack preferences and work down until it finds criteria matching one of the unstack pairings. Provided that pairing has not been requested by and assigned to a senior bidder, I will receive the pairing. (If unstacking does not affect me, Prefbid will not need to consider my unstack preferences; it will look only at my other bid sheets.)
Under a globalized system, I do not think such selection of unstack pairings is possible. So to compare and contrast:
SmartPref: Pilots know if they are in the constrained group, but they have no way of preferencing which pairings they might receive?
Prefbid: Pilots may not know for sure if they will be unstacked, but they have complete control of ordering all unstack pairings according to their preferences.
Just as prefbid will not assign you a pairing that has been requested and assigned to a senior bidder, smartpref does the same in the constrained group as well. The difference is that you see it right away and can bid accordingly just as you do with your unstacked preferences. The way you tell the system what you want through your bidding may be different but it sounds like the end result is the same , as far as unstacking goes.
