How do you run pilot bidding and crew pairings for a Part 121 airline?

Run LINE and PBS pilot bidding, crew pairings, a duty board, reserve and trip-trading on one system, with FAR 117 and 121.467 duty-rest legality checked by deterministic, line-by-line rules — never guessed. AviationAlley awards bids with that rules engine; an AI pairing optimizer can suggest up to five ways to rebalance credit-hour spread and layovers, but you decide every award.

Pilot bidding at a Part 121 carrier lives or dies on two things: giving crews the lines they actually want, and never awarding a pairing that busts duty-rest legality. AviationAlley is a multi-vertical aviation operations platform that handles both in one place — LINE and PBS bidding, crew pairings, a duty board, reserve and trip-trading — with the legality call made by deterministic FAR rules you can put in front of an inspector. AviationAlley is pre-launch; what follows is how the Part 121 bidding and crew module is built to work at launch for founding-cohort airlines.

Why the answer is what it is

LINE and PBS bidding, built for Part 121

The crew module runs both LINE and PBS-style bidding alongside crew pairings, a duty board, reserve and trip-trading. It's the same workflow your pilots already expect, consolidated onto one system instead of a bid stack bolted to a separate scheduling tool.

Legality checked by deterministic rules, never guessed

FAR 117 and FAR 121.467 duty-rest legality is checked by deterministic, line-by-line FAR rules — same inputs, same answer, every time, with no probabilities and no black box. That's the part that has to be defensible when an inspector questions a finding, so it deliberately is not AI.

Bid awards stay deterministic — the AI only advises

The actual awards are run by the deterministic bidding engine. An AI pairing optimizer sits beside it and can suggest up to five ways to rebalance bid-line credit-hour spread and tighten layovers, but it never auto-awards — you decide which suggestion, if any, to take.

A plain-English explainer for every risk score

When a pilot's fatigue-risk score moves, the AI risk explainer narrates exactly which factors are driving it. The score itself is computed by the deterministic risk engine; the AI only puts the reasoning into words, so a number is never a mystery you have to defend blind.

Dispatch watch keeps crew limits in view

The Dispatch watch brief folds crew nearing a FAR 117 cap together with grounded tails, open MELs and weather into one 'what needs attention now' read for the dispatcher — so a looming duty-limit problem surfaces before it forces a last-minute scramble.

AI is off by default, with nothing half-working

Every AI surface — the pairing optimizer, the briefs, the risk explainer — hides itself when no API key is set. The deterministic bidding, legality and scoring engines run regardless, so a demo, test center or offline operation never meets a half-working feature.

What to look for

  • Run LINE and PBS bidding on one system, not a bolted-on bid stack
  • Confirm FAR 117 / 121.467 legality is checked by deterministic rules, not estimates
  • Keep bid awards on the deterministic engine — treat the AI optimizer as advisory only
  • Use the pairing optimizer's up-to-5 suggestions to rebalance credit-hour spread and layovers
  • Read the plain-English explainer behind every fatigue-risk score before acting
  • Watch the Dispatch brief for crew nearing a FAR 117 cap
  • Keep reserve and trip-trading in the same duty board as bidding
  • Verify AI surfaces hide cleanly when no API key is set

Related questions

Does the AI decide which pilot gets a line?

No. The deterministic bidding engine runs the actual awards. The AI pairing optimizer only suggests up to five ways to rebalance credit-hour spread and layovers, and it never auto-awards — you decide every award.

How is FAR 117 and 121.467 legality checked?

By deterministic, line-by-line FAR rules — same inputs, same answer, every time, with no probabilities and no black box. It's built to be defensible in front of an FAA inspector, which is why it isn't AI.

What can the crew module handle besides bidding?

Crew duty boards, crew pairings, reserve and trip-trading, plus a Dispatch watch brief that flags crew nearing a FAR 117 cap alongside grounded tails, open MELs and weather.
