Open the Targeting reportFleet counts are US registrations held directly by UNITED AIRLINESin the FAA registry (July 2026 snapshot). Aircraft registered to leasing and finance trusts (~26% of the US commercial fleet) can't be attributed to their operator and are excluded — these counts understate true fleet sizes, especially for lease-heavy operators. AD counts are distinct airworthiness directives linked to each fleet family in our corpus — the same value for every operator of that family; a compliance-demand signal, not a safety ranking.
