Portsmouth International Airport at Pease

Portsmouth International Airport at Pease, formerly known as Pease International Airport, is a joint civil and military use airport located one nautical mile (2 km) west of the central business district of Portsmouth, a city in Rockingham County, New Hampshire, United States. It is owned by the Pease Development Authority. It is included in the Federal Aviation Administration (FAA) National Plan of Integrated Airport Systems for 2017–2021, in which it is categorized as a non-hub primary commercial service facility.

The airport is located within the Pease International Tradeport, a result of the ongoing redevelopment of the former Pease Air Force Base which was closed under Base Realignment and Closure (BRAC) Commission action in the late 1980s and early 1990s.

Military
The airport shares its runway with the Pease Air National Guard Base, which is actively utilized by the 157th Air Refueling Wing (157 ARW) of the New Hampshire Air National Guard, an Air Mobility Command (AMC)-gained Air National Guard unit operating KC-46A Pegasus aerial refueling tankers. The 64th Air Refueling Squadron (64 ARS), an active duty Air Force unit of the 22nd Air Refueling Wing (22 ARW) at McConnell AFB, is also embedded and located with the 157 ARW at Pease ANGB.

Pease was one of seven Launch Abort Sites and one of 18 Emergency Landing Sites for NASA Space Shuttle orbiters.

Civilian
Domestic and international terminal passenger service by the third iteration of Pan American Airways began in 1999 and lasted until the airline's demise in 2004. This version of Pan American (also known as "Pan Am III") had its corporate offices located in Portsmouth and in 2001 was operating Boeing 727-200 jet service nonstop and also direct one stop to Orlando Sanford International Airport in Florida in addition to nonstop flights to Bangor, Maine and Worcester, Massachusetts with direct service also being offered to San Juan, Puerto Rico via Orlando. Other scheduled passenger airlines included Business Express Airlines operating Delta Connection service via a code sharing agreement on behalf of Delta Air Lines in the early 1990s, Allegiant Air (2005–2007), and Skybus Airlines (2007-2008). According to the Official Airline Guide (OAG), in early 1994 Business Express operating as the Delta Connection was operating up to fourteen flights every weekday into the airport with nonstop as well as direct one stop services from Boston (BOS), New York LaGuardia Airport (LGA) and New York Newark Airport (EWR) flown with Beechcraft 1900, Saab 340 and Short 360 commuter turboprops. The January 1994 OAG also lists nonstop service from New York Newark Airport being operated twice every weekday by Atlantic Coast Airlines flying United Express service via a code sharing agreement on behalf of United Airlines with British Aerospace BAe Jetstream 31 commuter propjets. Frontier Airlines began offering service to their hub in Orlando, Florida, on December 6, 2018, but abandoned the route after only 6 months.

Allegiant Air then returned in October 2013, and currently offers nonstop jet service flown with Airbus aircraft to several destinations. An expanded passenger terminal opened on January 22, 2021, for customers of Allegiant Air.

On Wednesday July 10, 2024, Breeze Airways announced service to Orlando, Florida and Fort Myers, Florida beginning October 9th and 10th respectively to Portsmouth utilizing the Airbus A220 on both routes.

The airport is the current base for PlaneSense, a company that offers fractional aircraft ownership programs.
