Part 121 · Pilot bidding (LINE + PBS)

LINE + rule-based PBS

Run awards in classic LINE mode or rule-based PBS, processed in seniority order so the senior bidder is served first. PBS reads each pilot's hard and soft preferences from a generic rule catalog, and the same package and bids always yield the same lines. What you get is a fair, explainable award — not the mechanics of how it's computed. It replaces the regional incumbents that force LINE-only.

Launching the first quarter of 2027.

What line + rule-based pbs gives you

  • Classic LINE mode or rule-based PBS
  • Processed in seniority order — senior bidder served first
  • The same package and bids always yield the same lines

How an operator uses this

A crew planner builds a monthly package per base × equipment × position and moves it through DRAFT → OPEN → CLOSED → AWARDED → PUBLISHED, so pilots, the desk, and the auditor all know exactly where the bid stands. Pilots bid from the portal, awards run in classic LINE or rule-based PBS in seniority order, and the award engine is a pure function — the same package and bids always produce the same lines. When a correction comes in, re-running cleanly replaces the prior awards rather than stacking duplicates, so there's no spreadsheet to rebuild by hand; pairings are built line by line inside the package, and pilots without an awardable line fall to a reserve pool.

Illustrative — every screen reflects what's in your own data, nothing more.
