Finding Cheap Flights From Ottawa

Ottawa is served by Ottawa Macdonald–Cartier International Airport (YOW), the capital's primary airport and a significant hub for government and business travel. It offers extensive domestic connectivity, strong transborder service to the northeastern USA, and a growing selection of direct international routes, particularly to sun destinations and key European hubs.

The most frequent and affordable flights from Ottawa are domestic routes to major Canadian cities. Key destinations include Toronto (YYZ), Montreal (YUL), Vancouver (YVR), and Calgary (YYC). For the United States, top routes include Chicago (ORD), New York (LGA), Washington (IAD), and Boston (BOS). Internationally, YOW offers direct flights to London (LGW), Frankfurt (FRA), various Caribbean destinations, and seasonal European services.

The market is competitive, featuring strong presence from both Air Canada and WestJet on domestic and transborder routes. Porter Airlines has significantly expanded at YOW, offering competitive fares to Toronto Billy Bishop (YTZ) and other eastern destinations. Low-cost carrier Flair Airlines operates select routes, while international carriers like Air Transat, British Airways, and Sunwing provide direct overseas service.

To secure cheap flights from Ottawa, book domestic and U.S. flights 4-8 weeks in advance. For direct international routes (especially to Europe), start monitoring prices 3-6 months ahead. Always compare fares between Air Canada, WestJet, and Porter, and consider Porter's convenient downtown Toronto connection (YTZ). Flying mid-week, especially on Tuesdays and Wednesdays, consistently offers lower fares. For government travelers, note that booking outside peak government travel times can yield significant savings.
