A quick glance at that inbound flight number for November showed only 23 results which were spread around a few bases in which that flight is associated with a pairing. IND had the most, followed by BOS, CMH, and just one or two for ORD, LGA, PHL, and DCA.
It may be more trouble than it’s worth because you gotta try and guess which bases will get those overnights while choosing the base that’s best to commute to/from. All while pairings and flying changes month to month among the bases.
Sorry, it’s a bit too involved to try and match that flight to a pairing, to an FO, and then check their seniority. Maybe there’s an easier way, haha, but I do not know of it.
