What happened
British Airways and Porter Airlines have announced a new codeshare agreement, effective June 24, 2026, with travel beginning July 8, 2026. British Airways customers can now book 17 Porter destinations across Canada under a British Airways flight number, extending BA's reach beyond its existing London-to-Toronto/Montreal/Vancouver routes. Earning Benefits: British Airways Executive Club members earn Avios and tier points on these Porter-operated flights. Earning is based on the price of the British Airways fare, not the operating carrier. For example, a one-way London to Calgary fare of £1,336.79 earns a Blue member 7,068 Avios and 1,404 tier points. The Avios are not split between segments but posted to one account. Booking Details: Flights are on sale now at ba.com. The Porter leg appears only when searched as a connection from a British Airways flight (e.g., London to Toronto, then Toronto to Calgary). Passengers benefit from one ticket, one baggage policy, and through-checked luggage. Context: This adds BA to Porter's growing list of oneworld partners, which includes American Airlines, Alaska Airlines, Qatar Airways, and Japan Airlines. Porter's fleet consists of Embraer E195-E2 jets with a 132-seat 'Elevated Economy' cabin featuring two-by-two seating, free Wi-Fi, and included beer and wine
