To understand how a New York City private jet tax could actually be implemented, you need to understand who controls the airports.

The Port Authority is a bi-state agency jointly controlled by the governors of New York and New Jersey with an annual operating budget of $10.1 billion and a proposed $45 billion capital plan from 2026 – 2035. It operates JFK, LaGuardia, Newark Liberty, and Teterboro — all rated high tax-risk under current political conditions. Teterboro Airport, which does not allow scheduled airline flights and only services private flights, handles approximately 177,000 arrivals and departures annually.

Westchester County Airport (HPN) is not a Port Authority facility. It is owned and operated by Westchester County — outside Mamdani’s direct political sphere and outside the joint gubernatorial control structure of the Port Authority. This makes it the most insulated major reliever airport in the New York metro under current political conditions.

Republic Airport (FRG) on Long Island is New York State property — its vulnerability depends on whether Governor Hochul aligns with Mamdani’s agenda, which remains an open question.

Key policy context: The Port Authority has the authority to set fees, surcharges, and access terms at its facilities without requiring standard legislative processes in many scenarios. The question isn’t just whether a tax gets proposed — it’s whether the mechanism to implement it already exists. In many cases, it does.
