As of October 27, 2026.


1. The official L/D reading is 36.1 for July and the September early read is 29.0 (AeroBaron, from BTS, EIA and BLS data), the lowest since early 2009.
2. Plan Q4 and Q1 assuming slower approvals and harder pushback on price from airline and operator customers.
3. Action: Review payment terms and open quotes with your top 10 customers this month, and lead every proposal with the cost it saves them.


1. This is a cost problem, led by fuel: October jet fuel is averaging $4.46 a gallon so far (EIA Gulf Coast, through Oct 20), about 112% above the same days a year ago.
2. Customers with big fuel bills tend to cut discretionary spend first, so plan for projects that aren't safety-critical to slip into next year.
3. Action: Add a fuel or cost escalator to any quote that runs into 2027, and re-price open bids older than 60 days.


1. Supply is normal at 51.0 for August (Census and BLS data): backlog covers 35 months, book-to-bill is 1.27 and parts prices are up about 1.7%.
2. Scarcity won't carry your pricing next quarter, so plan to win on turn time and reliability.
3. Action: Put your real turn times and on-time rate in every quote, and on your website where buyers and AI search can find them.


1. July puts us at L/D 36.1 and Hangar Pressure 50.9, which means customers are squeezed on cost but not short on parts.
2. Buyers can shop around right now, so plan for work to go to suppliers they already trust and can find fast.
3. Action: Call your top accounts before they start shopping, and check what AI search says when a buyer asks for a supplier like you.
