WestJet announced the introduction of direct booking for interline itineraries through its website, app and contact centre, combining WestJet flights with partner airlines in a single reservation.
According to the airline, the move will eventually give customers access to hundreds of additional destinations across six continents through nearly 50 interline partners.
The rollout begins with Copa Airlines, which is now available for booking.

“Direct channel booking for interline is a meaningful enhancement for our guests looking to explore new horizons," said Jared Mikoch-Gerke, WestJet Director, Airport Affairs and Alliances.
"They will enjoy benefits similar to a codeshare or WestJet operated itinerary, now with the luxury of more destinations. Whether they want to cross off a bucket list city like Lima or make their way to the Great Wall of China from Beijing, this change will make travel dreams within arm's reach for many more Canadians.”

The airline expects to expand direct booking capabilities to more than 10 interline partners by the end of 2026, adding more than 100 new destinations through partner networks.
Interline itineraries booked directly with WestJet can be managed through the airline’s own channels, including changes and cancellations. Passengers will also receive boarding passes and baggage tags through to their final destination at check-in.
WestJet Rewards will apply across the full journey, including partner-operated segments, and points can be used toward payment.
The first phase of the rollout focuses on expanding access to Central and South America through Copa Airlines. Travellers will be able to connect via WestJet’s Mexico destinations and Panama City to reach 37 cities across 18 countries, including Uruguay, Guatemala, Ecuador, Chile, Argentina and Peru.
More partners are expected to follow through 2026 and 2027, including Korean Air, Japan Airlines, Kenya Airways, LATAM Airlines and Saudia, further extending WestJet’s global reach into markets it does not serve directly.
