PAL Airlines (formerly Provincial Airlines) is a Canadian regional airline with headquarters at St. John's International Airport in St John's, Newfoundland and Labrador, Canada. PAL operates scheduled passenger, cargo, air ambulance and charter services. PAL is the commercial airline arm of the PAL Group of Companies. In addition to its head office, it also has bases in Halifax, Nova Scotia (Halifax Stanfield International Airport), Happy Valley-Goose Bay (CFB Goose Bay), and Montreal, Quebec (Montréal-Pierre Elliott Trudeau International Airport). PAL is the second largest regional airline operator in Eastern Canada next to Jazz Aviation. History The airline was established in August 1974 as a flight training and charter operator. Scheduled airline operations began in 1980. In the 1980s, the company also developed its airborne maritime surveillance division, which operated until 1989 as Atlantic Airways. In 1988, it acquired Eastern Flying Service (established in 1956 and operating an extensive air courier network and charter services). From 1995 to 1997 it used the brand Interprovincial Airlines to operate scheduled regional airline services in a commercial agreement with Air Nova. The Provincial Airlines brand was restored in 1997 to enhance network growth and focus on regional air transport needs. In 1988 PAL Airlines joined with the Innu Development Limited Partnership, to establish Innu Mikun Airlines, which grew to be the largest Labrador based air carrier providing charter services throughout Labrador and scheduled airline services to coastal Labrador communities. In 2017 PAL Airlines, Innu Development LP, and NGC Nunatsiavut established Air Borealis through a merger of Innu Mikun Airlines and Air Labrador to enhance indigenous aviation, expand and improve regional transportation infrastructure, and foster community economic growth. In its early years, the company operated light aircraft such as the Piper Navajo and the Britten-Norman Islander around Atlantic Canada. In 1988, the company introduced Fairchild Metroliners, initially for courier services and in 1989 in scheduled passenger services, eventually building one of the larger Metro fleets through the success of the aircraft in building regional air passenger traffic. From 1996 to 1998, it operated a Convair 580 for courier and cargo services. In 1995 the first DHC-6 Twin Otters were purchased for services in Labrador. In 2001, PAL took the delivery of its first Saab 340 aircraft. This meant that PAL Airlines had become a 705 carrier, as per the Canadian Aviation Regulations, maintained by Transport Canada, and thus the first class of flight attendants were trained
