WestJet is just over two months away from opening its first route to South America. On 15 December the Calgary-based carrier will start three-weekly Boeing 787-9 flights between Calgary International Airport and São Paulo Guarulhos, according to schedule details reported by Simple Flying on 8 October. At about 6,610 miles (10,635 km), São Paulo will become WestJet’s longest route, ahead of Calgary–Seoul, and the only nonstop passenger link between Western Canada and the South American continent.
A short inaugural season
WestJet originally planned to fly Calgary–São Paulo from 8 November through 18 April, then pushed the launch to 15 December and cut the season to 14 February. That turns a five-month winter schedule into roughly a two-month experiment even as the airline concentrates long-haul flying around Calgary.
Outbound flight WS54 is scheduled to leave Calgary at 23:55 on Tuesdays, Thursdays and Sundays and arrive in São Paulo at 15:45 the next afternoon after about 12 hours and 50 minutes. Return WS55 leaves at 19:40 and lands back in Calgary at 18:15 after 13 hours and 45 minutes. The airline will use its 320-seat 787-9, configured with 16 Business, 28 Premium and 276 Economy seats.
Why Calgary–São Paulo is a bet on connections
OAG data cited by Simple Flying show only about 10,000 passengers travelled between Calgary and São Paulo in 2025 — thin for a 320-seat Dreamliner three times a week. Vancouver alone generated about 42,000 São Paulo passengers, Seattle about 26,000 and Edmonton about 5,000, so WestJet will need feed from across Western Canada and the US Pacific Northwest.
At the São Paulo end, Guarulhos is LATAM’s main Brazilian hub. WestJet already has an interline with LATAM, and both carriers are linked through Delta’s equity stakes, allowing through-checked connections deeper into South America. WestJet says it is marketing links to more than 60 South American destinations, including Rio de Janeiro, Bogotá, Lima, Santiago and Buenos Aires.
Calgary’s 100th nonstop
São Paulo was announced as WestJet’s 100th nonstop destination from Calgary. Chief executive Alexis von Hoensbroech said the city has stood with the airline as it built that network and called the South America launch “the beginning of an exciting new chapter” in WestJet’s Calgary story. The brief initial season suggests the carrier is testing demand carefully with scarce Dreamliner capacity rather than locking in a full winter programme on day one.
Tickets and final timings remain subject to change. If loads hold through February, industry watchers will look for an extended 2027 winter season or a longer summer shoulder on the same city pair.
Belly cargo and corporate travel between Brazil and Western Canada are secondary revenue streams WestJet will also chase, especially given Calgary’s role as an energy and logistics hub. A Japan connecting angle via Calgary’s near-great-circle position on São Paulo–Tokyo routings has been floated in coverage, but the near-term test is simply whether local and connecting leisure traffic can fill a Dreamliner three times a week through a short Southern Hemisphere summer window.
