Who is in this cut

Included: airlines and regional carriers, airport ground-handling and catering contractors, aircraft and engine makers, avionics and airfoil shops, and defense and space primes and their suppliers.

What counts as aerospace, defense or airline here: the employer name reads as an airline, airways, air-lines, aviation, aeronautical, aerospace, aircraft, avionics, airfoil, missile or defense/defence business, or is one of ~25 named primes and carriers (Boeing, Lockheed, Raytheon, Northrop, General Dynamics, Spirit Aero, Pratt & Whitney, Textron, Gulfstream, Bombardier, SpaceX, Blue Origin, SkyWest, GoJet, JetBlue, and the United/Delta/American/Southwest air entities). Airport ground handling and catering contractors (Swissport, Menzies) are here rather than with logistics, because the work is airside — this is the deliberate counterpart of the logistics cut, which excludes airlines. A defense supplier trading under a name that says nothing about defense is not here; it is in the unclassified remainder of the sector dataset. Every row keeps the sector_rule that fired, so any inclusion can be disputed row by row.

Why this file exists

Airline and defense job cuts are followed nationally as company news, but the underlying filings — which airport, which plant, which town, how many workers, notice date, effective date, closure or layoff — sit on 48 separate state portals and are never assembled as one aerospace series. This file is that series, with the closure/layoff split the states themselves recorded.

The employers with the most airline, aerospace and defense notices on record

Counted per notice, not per event: a company that files in four states files four notices. Employer names are the resolved spelling — the raw agency spelling is kept in the download.

The 15 most recent airline, aerospace and defense notices

Date is the notice date where the agency publishes one, otherwise the layoff date. 172 of the 1,551 notices in this cut are recorded as a closure rather than a layoff.

How the industry is decided: no state WARN portal publishes an industry field, so there is no NAICS column to filter on. The sector here is assigned from the resolved employer name by a published rule table (19 sectors, 3,152 patterns, first match wins), and every row carries the pattern that fired in its sector_rule column so you can audit or re-cut it. The archive holds 61,428 notices; 61,232 of them carry a usable date and are in the sector file (196 have no date in either column), 32,168 come out with a sector, and 29,064 stay unclassified — and are still counted in every total shown anywhere on this site. Manual audit 2026-09-12: 4 of 60 sampled rows were assigned to the wrong sector. Rebuilt 2026-09-24.

How to check any of this

Every number on this page is computed at build time from notices_by_sector.csv (one row per notice, with the sector and the rule that assigned it), and the yearly series from sector_by_year.csv. The free HTTP API serves the whole archive as JSON, NDJSON and per-state CSV with no key. This industry is also published as its own Hugging Face dataset, and the full sector cut as one file. If a number here disagrees with the file, the file is right and it is a bug — tell us and it is fixed the next morning.
