Part 121 · Network-aware scheduling
Crew-base efficiency
Pairings are scored against your crew bases, surfacing deadhead legs and out-of-base overnights, so the desk can favor pairings that begin and end at a crew member's domicile and feed that into the bidding award run. It replaces judging which pairings strand crew away from base by reading the lines one at a time.
Launching the first quarter of 2027.

Who it's for
Crew planners at a Part 121 operation who, once this ships, want which pairings strand crew away from base surfaced rather than judged by reading the lines one at a time.
What it replaces
Judging which pairings strand crew away from base by reading the lines one at a time.
What crew-base efficiency gives you
- In development — will score pairings against your crew bases
- Surfaces deadhead legs and out-of-base overnights
- Favors pairings that begin and end at a crew member's base
Deadhead and out-of-base overnights surfaced
This capability is in development. Once it ships, pairings will be scored against your crew bases, surfacing deadhead legs and out-of-base overnights so the desk can favor pairings that begin and end at a crew member's domicile. It is not yet in production, so today the desk still reads pairings against base by hand.
- In development — will score pairings against your crew bases
- Surfaces deadhead legs and out-of-base overnights
A signal that would feed the award run
As planned, the crew-base signal will feed into the bidding award run so pairings that begin and end at a crew member's base can be favored there. The intent is to replace reading the lines one at a time — but it is not yet in production, and the desk judges base today by hand.

How it works
Crew-base efficiency, step by step
Planned: pairings will be scored against your configured crew bases.
Planned: deadhead legs and out-of-base overnights will surface on the view.
Planned: the desk will be able to favor pairings that begin and end at a crew member's base.
Planned: the signal will feed into the bidding award run.
Questions
Crew-base efficiency — frequently asked
Can it surface out-of-base overnights today?
Not yet — crew-base efficiency is in development. When it ships, it will score pairings against your crew bases and surface deadhead legs and out-of-base overnights.
What problem will crew-base efficiency address?
It is planned to surface which pairings strand crew away from base — deadhead legs and out-of-base overnights — so the desk can favor pairings that begin and end at a crew member's domicile, instead of reading the lines one at a time.

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.
