Sunwing Airlines was a Canadian leisure carrier founded in 2005 and based in Toronto, known for its orange branding and close ties to Sunwing Vacations, one of Canada’s largest tour operators. WestJet acquired Sunwing in May 2023, and after a two-year integration process, Sunwing Airlines flew its final flight and was fully merged into WestJet’s single operating certificate on May 28, 2025, ending nearly 20 years of independent operation.
Sunwing Airlines Route Network
Sunwing’s former leisure routes to the Caribbean, Mexico, and Central America are now flown by WestJet, which absorbed Sunwing’s aircraft, routes, and the Sunwing Vacations tour brand as part of the completed merger.
Primary Hub
Toronto Pearson International Airport (YYZ) — historical
Sunwing’s historical bases included Toronto Pearson (YYZ), Montréal–Trudeau, Calgary, Ottawa, and Vancouver — all now WestJet operations following the 2025 integration.
Alliance & Partner Airlines
As a merged-away airline, Sunwing has no current independent alliance ties. Its former flying is now part of WestJet, which is not itself a member of Star Alliance, oneworld, or SkyTeam.
Baggage, Seating & Onboard Amenities
A quick reference before you pack — always confirm exact allowances on your fare rules at booking, since they vary by route and cabin.
Carry-On & Personal Item
Not applicable under the Sunwing name — book through WestJet, whose current carry-on rules now apply to all former Sunwing routes.

Excess Baggage Fees
Overweight, oversized, or extra bags typically incur a per-bag fee charged at check-in or online in advance — pre-paying online is usually cheaper than paying at the airport.
Seat Selection & Cabin Classes
Not applicable under the Sunwing name — WestJet’s standard cabin configuration (Premium, Economy, Extended Comfort, and UltraBasic) now applies across the unified fleet, including former Sunwing aircraft.

WestJet acquired Sunwing in 2023 as part of a strategy to consolidate its position in the Canadian leisure and vacation-package market, and announced in June 2023 that it would eventually fold Sunwing into its mainline operations rather than keep it as a separate brand — a process completed in May 2025.
Yes — Sunwing Vacations, the tour operator brand, continues to operate as one of Canada's largest vacation package sellers, now booking travelers onto WestJet-operated flights instead of Sunwing Airlines aircraft.
