Peninsula Airways, operating as PenAir, is a U.S.-based regional airline headquartered in Anchorage, Alaska. It is Alaska's second largest commuter airline operating scheduled passenger service, as well as charter and medevac services throughout the state. Its main base is Ted Stevens Anchorage International Airport. PenAir currently has a code sharing agreement in place with Alaska Airlines with its flights operated in the state of Alaska.
Peninsula Airways was founded by Orin Seybert in 1955. Seybert was 19 years old, living in Pilot Point, Alaska and owned a 1946 two-seat Taylorcraft. In 1956, a four-seat Piper Tri-Pacer was added. On March 1, 1965 Peninsula Airways became incorporated and purchased the fixed base operation ( FBO) in King Salmon.
In 1969, Peninsula Airways acquired all assets of Tibbetts-Herre Airmotive, which had operated from Naknek since 1950. By 1973, regular service was provided between King Salmon and the Pribilof Island communities, St. Paul and St. George. Charter service was also extended into the Aleutian Islands, Dutch Harbor, Atka and Adak with Grumman G-44 Widgeon amphibious aircraft.
In 1977, two Grumman Goose amphibious aircraft were purchased from Reeve Aleutian Airways, and the sub-contract was expanded to cover all locations certificated to Reeve throughout the Alaskan Peninsula and Aleutian Islands. This required setting up an operating base at Cold Bay, with hangars, offices and employee housing.
In 1980, the Civil Aeronautics Board awarded a Part 401 Certificate of Public Convenience and Necessity to Peninsula Airways, and all aircraft operations were conducted under Part 135 of the Federal Air Regulations.
In 1983, Peninsula Airways acquired its first turboprop: a Cessna Conquest operated out of Cold Bay. Peninsula Airways was the first Alaskan air carrier to qualify for CAB Part 419 subsidy, allowing the airline to operate Essential Air Service (EAS) routes to Atka, St. George and Kodiak Island.
In 1985, Peninsula Airways acquired all assets of Air Transport Service, Inc., based in Kodiak. Included in the deal was a hangar and office facility with approximately six aircraft and scheduled year-round service to all points on the Island. A base was established in Anchorage with two Cessna Conquest turboprops offering charter service from Anchorage to the Pribilof Islands. Scheduled service from Anchorage to King Salmon and Dillingham was added a year later.
The first Fairchild Swearingen Metroliner propjet was placed into service in 1987 and Metro aircraft remained in the fleet until 2011.
In 1988, several bush operators in Dillingham had their certificates revoked by the Federal Aviation Administration (FAA), prompting Peninsula Airways to set up an operation there. A hangar and aircraft were purchased and service to the surrounding communities began.
In 1989, Peninsula Airways was contracted by Exxon to support the Exxon Valdez oil spill cleanup. At the same time, a contract was awarded to Peninsula Airways by Alaska Regional Hospital to provide 24-hour medevac service. Peninsula Airways' operations were inspected and approved by Exxon Corporation, U.S. Department of the Interior Office of Aviation Services (OAS), U.S. Department of Defense, and two ( FAA) NASIP "white glove" inspections.
In 1991, Peninsula Airways began doing business as PenAir and became a code sharing and Mileage Plan partner with Alaska Airlines. PenAir transitioned to FAA Part 121 regulations in 1996, operating under both Part 135 and 121. PenAir was the first regional airline in the United States to make the 10-19 seat required conversion, including a dispatch department.
The airline expanded its operations outside of Alaska in 2012 after bidding on and being awarded Essential Air Service routes in the Northeastern United States. It established a hub at Boston's Logan International Airport and started operating service to Presque Isle, Maine and Plattsburgh, New York, with additional seasonal service to Bar Harbor, Maine.  
PenAir's presence in the continental United States greatly expanded in 2016 when the airline was awarded multiple Essential Air Service routes in the Midwestern and Western United States. The airline established its third and fourth hubs at Denver International Airport and Portland International Airport. From Denver, PenAir operated service to Dodge City and Liberal, Kansas and Kearney, North Platte, and Scottsbluff, Nebraska.  From Portland, PenAir operated Essential Air Service to Crescent City, California and also began service to Arcata/Eureka and Redding, California and Klamath Falls and North Bend/Coos Bay, Oregon.
On August 7, 2017, PenAir filed for Chapter 11 bankruptcy. PenAir made the decision to end all flights out of its Denver and Portland hubs. Routes in California and Oregon that weren't funded by Essential Air Service subsidies were terminated within days. The terms of the Essential Air Service contract required that PenAir continue to operate those routes until a new airline could be awarded the contract, a process expected to be completed within 90 days.   On August 30, 2017, PenAir announced it would cease all Denver operations effective after September 10, 2017 due to a mass resignation involving 17 crew members. 
On November 30, 2017, PenAir announced it would end its service to Crescent City, California as of December 15. The city has chosen Contour Airlines to operate the Essential Air Service route, but PenAir stated it would be unable to continue the service until Contour begins operating. 
On May 30, 2018, PenAir cancelled service via Boston to and from Plattsburgh, Bar Harbor and Presque Isle a month early, citing staffing issues, breaking their Essential Air Services contract with the Department of Transportation.     
As of March 2019 the PenAir fleet consists of the following aircraft: 
PenAir is currently the only air carrier in the U.S. operating the Saab 2000 regional turboprop in scheduled passenger airline service.
PenAir was among the last airlines in the world to operate the Grumman G-21A Goose seaplane on scheduled flights. This piston powered amphibious aircraft was used to resupply remote coastal locations where no land-based airstrip existed. On December 21, 2012, the Grumman Goose made its final commercial flight from Unalaska to Anchorage.  PenAir also previously operated another piston powered amphibious aircraft type being the Grumman G-44 Widgeon.
The airline also previously operated several turboprop powered aircraft types including the Cessna 208B Grand Caravan, Cessna 441 Conquest, as well as the Metro II, Metro III and Metro 23 variants of the Fairchild Swearingen Metroliner.
According to the July 1, 2016 Alaska Airlines system timetable, PenAir is currently operating all of its code sharing flights in the state of Alaska on behalf of Alaska Airlines with Saab 340B and Saab 2000 turboprop aircraft with the Saab 2000 being a larger, high speed version of the Saab 340B while all Alaska Airlines code sharing flights in the lower 48 states in the U.S. are operated by PenAir with the Saab 340B.
