Air Transat and Porter Airlines, two of Canada's most prominent airlines, have launched a new bilateral codeshare. The agreement is now activated between Porter Airlines' domestic flights to and from Halifax (YHZ) and Toronto City (YTZ), and select Air Transat flights to and from Montreal (YUL).

Air Transat is now using its "TS" code on flights operated by Porter Airlines between Toronto's Billy Bishop and Montreal as well as between Halifax and Montreal. Travellers are then able to easily connect to or from a destination served by Air Transat via Montreal. This winter, connections to and from Paris, London and Lisbon are available, as well as domestic and several South destinations. Additional connection to and from the United States will be rolled out later this year.

In an upcoming phase, Porter Airlines will also use its "PD" code on select flights operated by Air Transat between Montreal and its destinations in Europe, the United States and Canada, pending receiving the required regulatory approvals.

Codesharing expands the range of routes and destinations for travellers, including the possibility of combining flights from both carriers on a single ticket, plus baggage check-in to the final destination. Passengers are also protected in the event of a flight delay or cancellation.

Codeshare flights are currently available for bookings made via Air Transat. Flights may be booked for departures as of November 2, 2022.
