Sunwing Airlines does not fly anymore. The last flight under that name landed on May 28, 2025. So the Sunwing baggage allowance you are researching is really WestJet’s, dressed in familiar branding.
That merger is the whole story behind the Sunwing baggage allowance today. There is no separate Sunwing policy left to check. The rules that matter are WestJet’s, plus a couple of extras that Sunwing Vacations still promises its own customers.
What happened to Sunwing Airlines
WestJet Group bought Sunwing Vacations Group in 2024. It finished folding the airline into WestJet by the end of May 2025. The former Sunwing jets now fly under WestJet’s single operating certificate.
Sunwing Vacations remains a real brand. Travelers still book package trips through it. But Sunwing Airlines the carrier is gone.
Sunwing’s own site confirms it. Flights from November 25, 2025 operate under WestJet. Baggage follows WestJet’s terms, not a separate Sunwing rulebook.
The Sunwing baggage allowance, explained
WestJet allows one carry-on bag at 22 by 9 by 14 inches, or 56 by 23 by 36 cm. You also get one personal item at roughly 16 by 6 by 13 inches, or 41 by 15 by 33 cm. There is no published weight cap on the carry-on.
The real rule is simpler than a number. You must be able to lift the bag into the overhead bin yourself, per WestJet’s carry-on page. Staff can and do check bags that will not fit.
The catch sits with UltraBasic, the cheapest fare WestJet sells. UltraBasic gets you a personal item only, with no overhead bag. Fly to Europe or Asia, or pay for Extended Comfort, and the carry-on bag comes back.
Most Sunwing Vacations packages book a fare that includes the carry-on bag. A bare flight booked on the lowest fare can lose it. Check your fare type before you pack two bags.
Checked bags and the free first bag perk
WestJet caps a checked bag at 62 total inches, or 158 cm. The weight limit is 50 pounds, or 23 kg. Go past either number and fees apply.
Oversize starts at 63 inches, or 158 cm, and runs to 80 inches. Overweight starts at 51 pounds and runs to 100 pounds on most routes. Both fees scale with fare and route.
Sunwing Vacations still offers a real perk on top of that baseline. The first checked bag is free for each traveler on a Sunwing vacation package flying WestJet. Certain package types and flight only bookings are excluded, so read your confirmation closely.
| Where you add the extra bag | Second bag fee |
|---|---|
| Online in advance | From 60 CAD plus tax |
| Web check-in | From 75 CAD plus tax |
| At the airport | From 85 CAD plus tax |
Add a bag at the gate and you pay the top rate. Add it online days ahead and you save real money on a family trip. The old advice about airline baggage fees still holds, even though the carrier behind Sunwing changed.
What travelers are asking since the switch
Frequent flyer forum threads show real confusion since the changeover. Travelers ask whether a Sunwing vacation flight, now flown under a WestJet certificate, still earns WestJet Rewards points. The booking runs through Sunwing Vacations, not westjet.com, so the answer is not obvious to most travelers.
Coverage of the merger describes the goal as a more consistent product. That phrase lines up with years of traveler reports about Sunwing’s old flights. Those flights, run more like charters, enforced carry-on and check-in rules unevenly from route to route.
Under one certificate, the Sunwing baggage allowance should now be the same everywhere. Travelers used to the looser leisure charter style are the ones most likely to get caught out. A WestJet gate agent will size your bag the same way in Toronto and Orlando.
Run your bag through the carry-on size checker before you pack. It is faster than guessing against the numbers above.
How this compares to other Canadian leisure carriers
Fly a similar route on Air Transat or Air Canada and the carry-on math is close. Canadian carriers cluster around the same overhead bin size. The real gap is elsewhere.
Sunwing Vacations still guarantees a free first checked bag on package trips. A plain WestJet booking on its lowest fare does not always include that. Read our guide to checked baggage before you assume the perk applies to your trip.
The bottom line
The bottom line on the Sunwing baggage allowance is simple. It is WestJet’s baggage policy wearing a familiar name, plus one genuine extra: a free first checked bag for package travelers. Confirm your fare type and your booking channel before you fly, because both change what you get for free.
