Québec City's airport, also known as Jean Lesage International Airport (IATA: YQB), is the primary airport serving Quebec City. Designated as an international airport by Transport Canada, it is located eleven kilometres west-southwest of the city.

 Québec City's airport offers quality, efficient and secure services and infrastructure capable of sustaining growth in air traffic to consolidate its role as a major socioeconomic force in the greater Québec City area's one of the 12th-busiest airports in Canada more than ten airlines offer 360 weekly flights to destinations across Canada, the United States, Central America, Mexico, the Caribbean and Europe.

Québec City's Airport receives various long--, mid- and short-haul aircraft. The airport has two runways. Its longest runway northeast-southwesterly direction is 06/24, having a length of 9,000 by 150 ft. Runway 24 is YQB's main approach pattern, which is equipped with area navigation (RNAV), required navigation performance (RNP), and a non-directional beacon (NDB) approach. Runway 06 has the same approach with adding an instrument landing system (ILS).

Québec City's airport adventure began in 1929, just two years after Charles Lindbergh's historic flight from New York to Paris. The city's first airport hangars are built in Sainte-Foy, the same location where the Centre Hospitalier de l’Université Laval (CHUL) now stands. It wasn't until the start of World War II that a real airfield was built in Ancienne-Lorette, where the first hangars were constructed for the Royal Canadian Air Force and the 8th Observer School. It is on this site that the first military flight registered in Québec took place on September 11, 1941.

In 2000, Transport Canada, until then the owner of the entire facility, transferred the airport's management, operations and development to Aéroport de Québec Inc., a local group of affiliates from the socioeconomic community wanting to keep airport operations in Québec City and maintain the economic vitality of the provincial capital. In the years that follow, the new management sets a goal of providing Québec City and the eastern part of the province with infrastructure that meets the expectations and needs of the different socioeconomic and political stakeholders of the region. A major modernization project was launched in 2006, paving the way for Québec City Jean Lesage Airport as it entered a new era, and once completed, the new airport terminal was inaugurated in 2008.

The largest expansion and redevelopment project in the airport's history is now underway. Some $277 million will be invested in the expansion to support the growth of the terminal. The YQB 2018 is a major undertaking of more than a dozen construction projects and includes the implementation of state-of-the-art technology. The objectives of the project include doubling the terminal area to offer more services and provide a more enjoyable experience for travellers. In terms of technology, much effort is going into simplifying procedures and improving the passenger experience: self-serve customs area, automated baggage drop-off, charging stations for phones and tablets, dynamic communication and signage systems... Technological possibilities are endless and the airport wants its customers to enjoy the full benefits it can offer. More space, more parking spots, more services...
