Winnipeg James Armstrong Richardson International Airport

In 1962, Stevenson Field was officially renamed Winnipeg International Airport, followed in 1997 by the airport's transfer to the control of the Winnipeg Airports Authority.[12]

The airport was briefly served by Scandinavian Airlines (SAS) during the mid 1950s on the world's first regular Polar route, which linked Copenhagen and Los Angeles with Douglas DC-6B propliner flights via Søndre Strømfjord, Greenland and Winnipeg.[14][15] By 1962, Trans-Canada Air Lines (TCA, now Air Canada) was operating weekly nonstop service between Winnipeg and London Heathrow Airport with Douglas DC-8 jetliners.[16] In 1963, Northwest Airlines was serving the airport with Lockheed L-188 Electra turboprops operated on multi-stop routings of Winnipeg - Grand Forks, ND - Fargo, ND - Minneapolis/St. Paul - Milwaukee - New York City Idlewild Airport (now JFK Airport) and also Miami - Fort Lauderdale - St. Petersburg, FL - Atlanta - Chicago O'Hare Airport - Minneapolis/St. Paul - Fargo, ND - Grand Forks, ND - Winnipeg.[17] By 1970, Air Canada was operating twice weekly nonstop service to Glasgow, Scotland, with both flights continuing on to London Heathrow, a weekly nonstop flight to London Heathrow, a twice weekly nonstop to Copenhagen with both flights continuing on to Frankfurt and a weekly nonstop to Frankfurt with this flight continuing on to Zurich with all of these services being operated with Douglas DC-8 jets as part of Air Canada's "Western Arrow" international flights at the time.[18] Also in 1970, CP Air was operating direct, no change of plane Boeing 737-200 service to San Francisco via stops in Calgary and Vancouver.[19]

The original main terminal building was built in 1964, and was designed by the architectural firm of Green Blankstein Russell and Associates (subsequently GBR Associates and Stantec Limited). It was expanded and renovated in 1984 by the architectural firm of IKOY, and a hotel was built across from the terminal in 1998. The original main terminal building was closed on Sunday October 30, 2011 and has since been demolished.

Two airlines operating jet aircraft in passenger service were previously based at the airport: Transair (Canada) and Greyhound Air.[20][21] During the mid 1970s, Transair was operating Boeing 737-200 and Fokker F28 Fellowship jets in addition to NAMC YS-11 and de Havilland Canada DHC-6 Twin Otter turboprops on scheduled flights in Manitoba and Ontario provinces as well as the Northwest Territories and the Yukon with service as far west as Whitehorse and as far east as Toronto from its Winnipeg hub in addition to operating charter services from the airport with Boeing 707 jetliners with charter flights to Europe, the Caribbean and Mexico as well as to Florida, Hawaii and other destinations in the U.S.[22] The August 1, 1996 Greyhound Air timetable lists nonstop domestic flights operated with Boeing 727-200 jetliners from the airport to Calgary, Edmonton, Hamilton, Kelowna, Ottawa, Toronto and Vancouver with Winnipeg serving as the connecting hub for the airline.

According to the Official Airline Guide (OAG), six airlines were serving the airport with scheduled passenger flights in the spring of 1975: Air Canada operating Lockheed L-1011 TriStar wide body jetliners as well as Douglas DC-8 and McDonnell Douglas DC-9-30 jets, CP Air flying Boeing 727-100 and Boeing 737-200 jets, the original Frontier Airlines (1950-1986) with Boeing 737-200 jets, Midwest Airlines operating de Havilland Canada DHC-6 Twin Otter commuter turboprops, Northwest Airlines flying Boeing 727-100 and Boeing 727-200 jets as well as McDonnell Douglas DC-10 wide body jetliners and locally based Transair (Canada) with Boeing 737-200 and Fokker F28 Fellowship jets as well as NAMC YS-11 turboprops.[23] In 1976, the OAG listed direct, no change of plane 737 jet service from both Denver and Las Vegas operated by Frontier with twice daily service from Denver and ten flights a week from Las Vegas, daily nonstop service from New York JFK Airport operated by Air Canada with DC-9-30 jets, daily nonstop 727-200 jet service from Chicago O'Hare Airport flown by Northwest, daily direct wide body DC-10 jet service operated by Northwest from Fort Lauderdale via stops at Chicago O'Hare and Minneapolis/St. Paul, twice daily direct 737 jet service from San Francisco flown by CP Air and a combined total of eight daily nonstop flights from Toronto flown by Air Canada and CP Air including twice daily wide body L-1011 jetliner service operated by Air Canada.[24] Two years later in 1978, CP Air was operating weekly nonstop Boeing 747 jumbo jet service to Honolulu as well as weekly nonstop Super Douglas DC-8-63 jet service to Amsterdam and by 1981 was operating McDonnell Douglas DC-10 wide body jetliner service from the airport.[25][26] Other airlines serving Winnipeg in the spring of 1981 besides Air Canada, CP Air, Frontier and Northwest included Nordair and Pacific Western Airlines both operating Boeing 737-200 jets (with the latter air carrier having taken over Transair), locally based Perimeter Aviation with Beechcraft and Swearingen Metroliner commuter turboprops and Republic Airlines (1979-1986) flying McDonnell Douglas DC-9-30 jets.[26]

Cross-border service from the U.S. in 1981 included an Air Canada nonstop flight from Chicago O'Hare Airport, Frontier nonstop service from Bismarck, ND and Minot, ND with these flights originating in Denver, Northwest nonstop service from Chicago O'Hare Airport, Grand Forks, ND and Minneapolis/St. Paul (with the latter route featuring wide body DC-10 service with this flight originating in Tampa) and Republic nonstop service from Duluth with this flight originating in Minneapolis/St. Paul.[27] In 1983, Air Canada was flying weekly nonstop service to London Heathrow Airport with Lockheed L-1011 TriStar series 500 long range wide body jetliners.[28] By 1985, Air Canada was operating direct one stop Boeing 727-200 service to Los Angeles via Calgary as well as direct one stop Boeing 727-200 service to LaGuardia Airport in New York City via Toronto and was also continuing to operate nonstop DC-9-30 flights to Chicago O'Hare Airport.[29] Also in 1985, Pacific Western was operating Boeing 767-200 wide body jetliners into the airport nonstop from Regina and Saskatoon as well as direct from Calgary and Vancouver in addition to operating Boeing 737-200 service while Northwest Territorial Airways (NWT Air) was operating Lockheed L-188 Electra turboprops configured for passenger/freight combi aircraft operations on nonstop flights between the airport and Rankin Inlet and Yellowknife.[30] In early 2000, CanJet was flying nonstop to Toronto with direct, no change of plane service to Montreal, Ottawa, Halifax and St. John's operated with Boeing 737-200 jets.[31] During the summer of 2003, Jetsgo, a start up air carrier which flew Fokker 100 and McDonnell Douglas MD-80 jets, was operating daily nonstop service to Toronto.[32]

On December 10, 2006, the Minister of Transport, Lawrence Cannon, announced Winnipeg International Airport was to be renamed Winnipeg James Armstrong Richardson International Airport in honour of the influential businessman and pioneer of Canadian commercial aviation from Winnipeg.[33]

Winnipeg's main airport terminal was designed by Argentine architect Cesar Pelli and Stantec.[34] The terminal's design was inspired by the City of Winnipeg's distinctive landscape and the province of Manitoba's vast prairies and sky.[35] It was the first airport terminal in Canada to be LEED-certified for its environmentally friendly concept, design, construction and operation.[36] The terminal was constructed in two phases, with construction beginning in 2007 and ending on October 30, 2011, when it was officially opened to the public.[37][38] Prior to the opening of the current main terminal building, a multi-level access road and four-level, 1,559 stall parkade were both opened in November 2006. All airlines serving Winnipeg International Airport operate at the main terminal building, with the exception of Perimeter Aviation.

Air Canada operates a Maple Leaf Lounge located in the domestic/international departures area (temporarily closed due to COVID-19),[39] and a "pay-in" lounge, operated by Plaza Premium Lounge (temporarily closed due to COVID-19), is also located in the domestic/international departures area.[40] Free WiFi is provided by the Winnipeg Airports Authority throughout the entire main terminal building.[41]

Perimeter Aviation is a regional airline that operates its own small, exclusive terminal building at Winnipeg International Airport to facilitate its passenger, cargo and charter services. Perimeter Aviation does not use the main terminal building due to its varied operations to small remote communities throughout Northern Manitoba and Northwestern Ontario using small propeller aircraft, with which regular airport terminal services (jet bridge, catering, etc.) are unnecessary and can actually be a hindrance to day-to-day operations.

The Perimeter Aviation terminal building is located 2.6 kilometres (1.6 mi) south of the main terminal building.

A large Canada Post mail processing facility was opened at the airport site on June 4, 2010.[42] The 23,225-square-metre (249,990 sq ft) facility is located east of the main terminal building, just north of Wellington Avenue. It is responsible for processing all mail and parcels for Manitoba, and some parts of Ontario and Northern Canada.

Three hotels are located on site, adjacent to the main airport terminal.

Richardson International Airport is included in a new 20,000-acre (8,100 ha) dry port created by provincial legislation—CentrePort Canada Act, C.C.S.M. c. C44—that will offer investment opportunities for distribution centres, warehousing and manufacturing.[43] CentrePort Canada will allow companies to take advantage of the cargo capabilities of Richardson International Airport, as well as serviced land, a mid-continent location and highway and rail transport.

On April 14, 2009, Prime Minister Stephen Harper with Premier Gary Doer announced at James Richardson that both the Federal and Provincial governments will contribute CA$212.5 million towards a divided four-lane expressway called CentrePort Canada Way. It is now complete, and links Inkster Boulevard to the Perimeter Highway on the north side of the CP Rail Glenboro subdivision parallel to Saskatchewan Avenue to attract new transportation logistics associated development to the city area west and Rosser Municipality northwest of the airport.

Winnipeg International Airport is located at 2000 Wellington Avenue in the City of Winnipeg. Several short and long term parkades are located on site, as well as a curb-side valet parking service.

Winnipeg Transit operates two bus routes that service the airport. A charging port has been added in October 2014 for Winnipeg transit's electric bus program. The Winnipeg Bus Terminal is a passenger and cargo bus terminal for intercity bus lines. Since Greyhound's exit from Western Canada, very few intercity bus routes, if any, have been serving the terminal. It is located beside the main terminal building. The Brandon Air Shuttle provides shuttle transportation between Winnipeg International Airport and Manitoba's second largest city, Brandon.
