Same numbers as the chart, straight from BLS. Dates are the first of each period, the way BLS reports them.
Air freight rose 5.8% over the last 12 months, but all of its main inputs rose faster: jet fuel +104.4%. That cost pressure may still pass through to prices.

A starting point citing this series by name and code. Replace the bracketed terms with your contract's actual scope before use.
The [affected portion] of the Contract Price shall be adjusted using US PPI — Scheduled Freight Air Transportation (BLS series PCU481112481112), published by BLS. Base Period: the index value published for September 2026 (or the month of contract signing, if different) is the Base Value. Adjustment: at each Adjustment Date, the Current Value is the most recently published three-month average of the index (the Averaging Window). The Escalation Factor equals Current Value divided by Base Value. Cap: the Escalation Factor applied under this clause shall not exceed 1.10 or fall below 0.90 (a 10% cap and floor) in any single Adjustment Date, regardless of the index's actual movement. [Replace bracketed terms with your contract's actual affected-portion definition and adjustment-date schedule before use. This is a drafting starting point, not legal advice.]
Covers commercial air cargo service, relevant to a time-sensitive freight contract where air is a real alternative to ocean or truck, not just an emergency option.
Split the contract into four categories: shipbuilding, ship parts, port equipment, and port equipment parts. Shipbuilding indexes to BLS PCU336611336611. Port cranes use PCU333923333923, a general lifting-equipment index that is a proxy, not an exact match. The two parts categories have no output index at all, so build those from a weighted input composite.
Escalake tracks US PPI — Scheduled Freight Air Transportation, applies your formula, and gives both sides a number they can confirm, no spreadsheet required.
