Part 117 vs. BID2606 · ONT 757/767

ONT 757/767: 3 of 52 lines pass.

Bid period 2606 (06 Sep – 01 Nov 2026), domicile ONT (Ontario, CA). Every line and every pairing evaluated against 14 CFR Part 117 as written — every pairing is a 2-pilot crew. Method, assumptions, and the other domiciles are on the hub page.

What this is — and is not. Part 117 does not currently apply to all-cargo operations; they fly under the older Part 121 Subpart Q/R/S limits and their collective bargaining agreements. Nothing on this page says any carrier is violating any regulation — every schedule analyzed here is legal as published under the rules that actually govern it. This is an independent what-if: if the cargo carve-out were removed tomorrow, how much of the bid period would survive? Congress is currently considering exactly that question (H.R. 7526, the Safe Skies Act; H.R. 7191, the Fatigued Pilot Protection Act). This analysis is not affiliated with, endorsed by, or produced for the FAA, any carrier, or any union.

The mechanism

Why pairings fail here.

116 of 240 pairings fail Part 117 on their own. Counts below are pairings touched by each rule.

Rule	Pairings	What it limits
§117.27	83	More than 3 consecutive night duty periods infringing the 0200–0559 circadian low without a qualifying reset.
§117.27*	8	A 4–5-night run legal only if the carrier scheduled ≥2 h of sleep-room rest during each night duty — the sits are long enough, but provision is not in the bid data.
§117.13 Table B	23	Scheduled flight duty period exceeds the Table B maximum for its report time and segment count (2-pilot).
§117.25(b)	6	A duty period begun without 30 consecutive duty-free hours in the trailing 168.

The verdicts

Every line with times.

CT = credit time per pay period · DO = days off · FDPs = flight duty periods · Night run = longest run of consecutive duty periods infringing the window of circadian low.

Reading the failures. Numbers such as 0281 are pairing (trip) identifiers in the pack. Sleep-room means the line is legal only if the carrier schedules ≥2 h suitable-accommodation rest during each consecutive night duty (§117.27's 5-night option). Line-caused failures come from how trips were placed on the line and could be fixed by line construction; all others are inherent in the pairing itself.

Line types with no times attached (RSSA ×6, RSSB ×8, RSVA ×14, RSVB ×7, RSVC ×2, VOR ×3, VTO ×5 — 45 lines) are excluded throughout: they carry no evaluable assignments.

The what-if, completed

Rebuilding the domicile to comply.

For this domicile the analysis went one step further: the same flying was rebuilt under Part 117 — compliant pairings kept, night runs split with crew swaps and deadheads, and the lines reconstructed under the same line-construction parameters.

	Published	Rebuilt under Part 117
Flying lines	48 (+4 standby)	41 full (+5 standby) + 16 partial lines
Trip occurrences on lines	332	403 (splitting adds parts)
Credit on lines	7,947:35	8,063:05 (+788:07 rig/deadhead credit, −672:37 flying left uncovered)
Deadhead legs added	0	188
Average days off, full flying lines	≈30 per 56 days	≈30 per 56 days
Lines passing Part 117	3 of 52	62 of 62

Roughly a third more pairing starts, a deadhead pair for every split, and about 788 additional credit hours in rig and deadhead pay for the same flying. The 23 pairings that exceed Table B could not be fixed by splitting — their 672:37 of credit is left for the company to re-time. Days off barely move: the cost is pairing count, deadhead volume, premium pay, and schedule redesign.

Both documents mirror the layout of the published bid reports, with the Part 117 duty-by-duty check shown for every pairing. Synthetic deadheads are placeholders timed to satisfy rest requirements, not real flight schedules.
