Part 121 · Pilot bidding (LINE + PBS)
Idempotent award engine
The award run is a pure function: feed it the same package and bids and it produces the same lines every time, and re-running cleanly replaces the prior awards rather than stacking duplicates. So you can re-run after a correction without fear of drift. It replaces the spreadsheet the crew desk rebuilds and re-checks by hand.
Launching the first quarter of 2027.
Illustrative — every screen reflects your own data.
Who it's for
Crew planners who re-run a closed bid after a late correction and need the second run to land cleanly instead of stacking a duplicate set of lines on top of the first.
What it replaces
The spreadsheet the crew desk rebuilds and re-checks by hand every time a bid input changes.
What idempotent award engine gives you
- A pure awards function — same inputs, same lines every time
- Re-running replaces prior awards instead of stacking duplicates
- Re-run after a correction without drift
A pure awards function
The award run is a pure function: feed it the same package and the same bids and it produces the same lines every time. Because the result is a function of the inputs, there's nothing to reconcile by hand and no drift between one run and the next.
- A pure awards function — same inputs, same lines every time
- No spreadsheet to rebuild or re-check by hand
- The same package and bids always produce the same lines
Re-run a correction without drift
When a correction comes in — a late bid fixed, a line added — re-running cleanly replaces the prior awards rather than stacking a second set of duplicates on top of the first. The crew desk can re-run after a correction without fear the result will drift.

How an operator uses this
The award run is a pure function: feed it the same package and the same bids and it produces the same lines every time. When a correction comes in — a late bid fixed, a line added — re-running cleanly replaces the prior awards rather than stacking a second set of duplicates on top of the first. That means the crew desk can re-run after a correction without fear the result will drift, instead of rebuilding and re-checking a spreadsheet by hand.

How it works
Idempotent award engine, step by step
Run awards against the closed package to produce the lines.
If a correction comes in, fix the input and re-run.
The re-run replaces the prior awards rather than stacking duplicates.
Confirm the result — the same inputs always produce the same lines.
Questions
Idempotent award engine — frequently asked
Can I re-run awards after a correction?
Yes. The award engine is a pure function — re-running cleanly replaces the prior awards rather than stacking duplicates, so you can re-run after a correction without drift.
Will re-running give a different result?
No. The same package and bids always produce the same lines, so a re-run with the same inputs is identical to the first run.

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.
