The FAA's periodic release of its updated Part 135 certificate holder and aircraft registry, compiled as of July 1, 2025, shows the on-demand charter fleet reaching 11,488 certificated tails — a modest increase from 11,467 in June and slightly above the 11,477 recorded at the start of 2025. Published and aggregated by Private Jet Card Comparisons on July 7, 2025, the list provides a structured record of every operator holding a Part 135 certificate under 14 CFR, along with the specific aircraft each is authorized to operate commercially. Data fields include the certificate holder name, certificate designator, FAA District Office, N-number, serial number, and aircraft model type, making the database searchable by both tail number and operator name.
For working pilots and aviation operators, the registry carries direct operational significance. Pilots flying under Part 91 or transitioning to Part 135 environments are legally responsible for understanding the regulatory boundaries of the certificate under which a flight is conducted. A specific tail number must appear on a valid Part 135 operating certificate before it can be used for compensation or hire on an on-demand basis — a fact that affects everything from crewing requirements and rest rules to maintenance standards and insurance obligations. Operators offering jet card or fractional-adjacent services must keep their fleet rosters current with the FAA, and any additions, removals, or certificate amendments are reflected in these monthly snapshots.
The broader context of this update is notable. Research indicates the FAA's public Part 135 operator list was temporarily taken offline for data corrections at some point following July 2025 — an event that drew attention from the National Air Transportation Association — before being restored to public access by early May 2026. That interruption underscored how dependent aviation consumers, charter brokers, legal professionals, and operators themselves have become on this database for due-diligence purposes. The NATA's public response to the outage reflected industry-wide concern about transparency in a market where verifying certificate legitimacy before a charter flight is considered a baseline safety practice.
The steady, incremental growth in certificated charter aircraft — even as the broader business aviation market has navigated post-pandemic normalization and pre-owned inventory tightening — suggests continued demand for on-demand air transportation and operator confidence in maintaining active certificates. For corporate flight departments operating under Part 91 that periodically dry-lease aircraft to Part 135 operators, or for pilots considering employment with charter companies, the registry serves as a real-time reference for verifying certificate status and fleet composition before committing to an operation. Regulatory professionals and aviation attorneys similarly rely on the list when conducting due diligence for aircraft acquisitions, mergers, or certificate transfers in the charter sector.
