Part 121 · Pilot bidding (LINE + PBS)
Crew pairing builder
Build and edit pairings line by line inside the package; pilots without an awardable line fall to a reserve pool. The pairings drive what each line actually flies. It replaces maintaining pairings in a document disconnected from the bid.
Launching the first quarter of 2027.
Illustrative — every screen reflects your own data.
Who it's for
Crew planners building the trips behind each line so the award run and the schedule reason about the same pairings, and tracking who falls to reserve when no line is awardable.
What it replaces
Maintaining pairings in a document disconnected from the bid they belong to.
What crew pairing builder gives you
- Build and edit pairings line by line inside the package
- Pilots without an awardable line fall to a reserve pool
- Pairings drive what each line actually flies
Per-line pairings inside the package
Pairings are built and edited line by line inside the bid package itself, so the trips a line flies live next to the bid they belong to rather than in a disconnected document. Because the pairings drive what each line actually flies, the award run and the schedule reason about the same trips a planner just built.
- Build and edit pairings line by line inside the package
- Pairings drive what each line actually flies
- Pairings live next to the bid, not in a separate document
A reserve-pool fallback
Pilots who don't land an awardable line fall to the reserve pool, so coverage and the lines it backs up sit in one place. Reserve isn't tracked off to the side — it's the same system as the lines it stands behind.
- Pilots without an awardable line fall to a reserve pool
- Reserve coverage lives with the lines it backs up

Questions
Crew pairing builder — frequently asked
Where are pairings built?
Line by line inside the bid package itself, so the pairings live next to the bid they belong to rather than in a separate document disconnected from it.
What happens to a pilot with no awardable line?
They fall to a reserve pool, so reserve coverage lives in the same system as the lines it backs up.

Deep diveMaintenance-station routing
Flags when a tail's due check won't reach a capable station before its limit. Advisory — it surfaces the risk, it doesn't block dispatch.
Deep diveCrew-base efficiency
Surfaces deadhead and out-of-base overnights so pairings can be built to originate and terminate at a crew member's base.
Deep diveWeighted efficiency score
A configurable weighted score (abstract points, lower = better) over deadhead, overnights, repositioning, and maintenance-fit slack — set your own weights.
Deep diveExplainable swap / re-base suggestions
Deterministic aircraft-swap and re-base proposals that improve the score — every suggestion shows its reasoning. Not AI, not a guaranteed optimum.
