British Airways and Porter Airlines have launched a new codeshare agreement that connects Porter’s growing Canadian regional network to British Airways transatlantic flights. This partnership is significant for frequent flyers who collect Avios and for those considering award redemptions through the transatlantic corridor. Here is what the agreement covers and how it affects award decisions for 2026.
Porter Airlines operates out of Toronto Billy Bishop, Ottawa, Montreal, and Halifax, with an expanding fleet of Embraer E195-E2 jets serving destinations across Canada and the northeastern United States. Under the codeshare, British Airways passengers can now book single-ticket itineraries that connect through Porter’s eastern Canadian hubs onto British Airways transatlantic services from Toronto Pearson and Montreal to London Heathrow.
For Avios collectors, the codeshare opens additional connection options when booking British Airways award tickets. A traveler in Halifax can now route through Toronto on Porter to connect to British Airways London flights, avoiding positioning flights on separate tickets. The single-ticket booking also provides protection if a Porter connecting flight is delayed and the London connection is missed.
The primary award decision facing frequent flyers is whether to use Avios for itineraries involving Porter connections versus alternative routings through United States hubs on American Airlines or other oneworld partners. Porter is not a oneworld member, so the codeshare does not extend to earning Avios or tier points on Porter-operated flights. However, the convenience of single-ticket booking through ba.com may make these itineraries preferable for travelers who prioritize simplicity over mileage earnings.
For those booking cash fares, the partnership means British Airways Executive Club members can earn Avios and tier points on the British Airways marketed segments of a codeshare itinerary. The Porter-operated connecting flights, however, will not earn Avios unless a future deeper integration adds earning opportunities.
The codeshare is most valuable for frequent flyers based in eastern Canadian cities not directly served by British Airways. Rather than positioning to Toronto or Montreal on separate tickets, travelers can now include the domestic connection within the British Airways booking. This reduces the risk of misconnects and simplifies baggage handling. For award travelers using Avios, this means cleaner routings with fewer separate bookings and lower positioning costs.
