AirTran Airways began service at the airport in 2006 with flights to Atlanta, Orlando and West Palm Beach.

In June 2009, Cape Air commenced service to Westchester with flights to Martha's Vineyard and Nantucket in Massachusetts.

In Summer 2022, they eliminated all flights out of White Plains except for subsidized essential air service routes from Lebanon.

This decision was made in the midst of COVID-19 pandemic-related air travel cuts, which drastically reduced commercial airline service to the airport.

Carrier shares (July 2023 - June 2024)[47] The IATA code for Westchester County Airport is HPN.

Some believe it is derived from the name of the city, White Plains (IATA codes normally do not begin with W because those are reserved for radio signals), while others maintain the IATA code represents the first letter of the airport's three neighboring communities, Harrison, Purchase, and North Castle.
