Holder and Operator Reports

Slot holder reports reflect the slot allocations as they are historically held. Holder reports do not capture ad hoc schedule adjustments or other short-term changes. The report status date reflects FAA confirmed slot transactions as of that date. In some cases, the reports do not reflect all transfers between mainline carriers marketing flights and the operating regional carriers. Slot holdings are subject to change without notice. Slot operator reports reflect the actual scheduled operation of slots and do not reflect slot holder standings.

John F. Kennedy International Airport (JFK)

LaGuardia Airport (LGA)


Ronald Reagan Washington National Airport (DCA)

Uneven Transfer Reports (JFK/LGA/DCA)

The Federal Aviation Administration (FAA) is responsible for administration of airport slot allocation at Washington's Reagan National Airport under 14 CFR part 93, subparts K and S and at John F. Kennedy International Airport and LaGuardia Airport under FAA Orders limiting scheduled operations at those airports. Slot allocation records are maintained by the FAA's Air Traffic Organization and all transfers of slots between operators are subject to prior FAA confirmation in accordance with the applicable rules.

The FAA maintains a list with an informal compilation of transfers of slots other than even, or one-for-one, slot trades at the same airport and excluding transfers between marketing carriers and the carriers operating flights on behalf of the marketing carrier. While the FAA considers the uneven slot transfers more likely than even trades to involve some form of consideration, the FAA has no information on consideration provided, if any, for slot transfers.
