British Airways can now sell you Porter flights to 17 Canadian cities

British Airways and Porter Airlines have signed a codeshare deal. It puts Porter's flights within Canada on ba.com under a BA flight number. BA announced the deal on June 24, 2026. Flights were bookable right away for travel from July 8, 2026.

If you fly BA between London and Canada, this gives you many more places to go once you land. Here is how it works, and where you can wait on the way.

Where you can go#

The deal covers 17 Porter destinations. You reach them by connecting in Toronto or Montreal on your way to or from London. The full list is:

• Western Canada: Calgary, Edmonton, Kelowna, Saskatoon, Vancouver, Victoria and Winnipeg
• Ontario: Ottawa, Thunder Bay and Toronto Pearson
• Quebec: Montreal (Trudeau), Montreal (Metropolitan) and Quebec City
• Atlantic Canada: Charlottetown, Deer Lake, Halifax and St. John's

That stretches from Victoria on the Pacific coast to St. John's on the Atlantic. Note that the list names Toronto Pearson, not Billy Bishop, the downtown island airport where Porter also flies. For a BA connection, Pearson is the airport that matters.

Why a codeshare matters#

A codeshare means you can book the whole trip in one transaction on ba.com. For example, you could book London to Toronto on BA and Toronto to Halifax on Porter as one ticket.

Booking on one ticket usually has two big advantages. Your bags are normally checked through to your final city. And if a delay on the first flight makes you miss the second, the airline is usually responsible for getting you there. If you book two separate tickets, you are on your own.

There is a limit to what a codeshare does. It does not make Porter a BA flight. The crew, the seat and the service are Porter's. BA's name is on the ticket, and BA handles the booking and the connection.

What Porter is like#

Porter is based in Toronto and flies to more than 40 destinations in North America, Central America and the Caribbean. It only sells economy, but BA's release points out a few things that set it apart:

• No middle seats, since seats are in pairs
• Free, fast Wi-Fi
• Free drinks served in real glassware
• Premium snacks

Porter calls this "Elevated Economy." If you're used to BA's Club World, it is still a step down. But for a short hop within Canada, it's more comfortable than many economy cabins. Our readers rate the airline 3.8 out of 5 on its Porter Airlines page.

Avios, tier points and status#

Members of The British Airways Club will earn Avios and tier points on Porter flights. BA has not said how many. It also hasn't said whether BA status gets you anything on Porter itself, such as priority boarding, extra bags or lounge access.

Porter is not part of oneworld, the alliance BA belongs to. So don't assume your Silver or Gold benefits carry over to Porter flights. The oneworld lounge rule, which lets Sapphire and Emerald members into partner lounges, applies only when you fly a oneworld airline. A Porter flight does not count.

Lounges on the way#

If you're connecting in Toronto to a BA flight to London, the British Airways Galleries Lounge at Pearson is the place to wait. Our users rate it 4.6 out of 5. It sits in Terminal 3, inside the Plaza Premium lounge complex upstairs from gate C32, and BA's section is run by Plaza Premium. It has a full bar and two showers. It is open to passengers in First and Club World, to members of The British Airways Club with Silver or Gold status, and to oneworld Sapphire and Emerald members. Club World passengers cannot bring a guest. Silver, Gold, Sapphire and Emerald members can bring one, as long as the guest is on a oneworld flight that day.

For the Porter part of your trip, there's no BA lounge. If you hold Priority Pass, Terminal 3 at Pearson has Plaza Premium lounges. The T3 International room rates 4.7 and has two showers. The T3 Domestic room rates 3.7. Check which terminal your Porter flight uses before you pick one.

In Montreal, BA does not have its own lounge either. Priority Pass members flying within Canada can try the Aspire Lounge (Domestic), which our readers rate 4.4 and which has a cocktail bar. Check the Toronto Pearson and Montreal-Trudeau pages for every option we track. See every BA lounge on our British Airways page.

What I'd do before you book#

Three practical points. First, compare the codeshare fare on ba.com with a separate Porter ticket. The one-ticket protection is worth something, but not at any price. Second, allow enough time between flights. Arriving from London means clearing Canadian immigration and customs, then checking in again for a domestic flight. Third, keep an eye out for BA to publish the Avios and tier point earning rates. Until it does, you cannot tell how much a Porter leg will move you toward status.
