Aer Lingus and British Airways continue to extend co-operation with each other under the umbrella of their parent company International Airlines Group.
The two airlines are now codesharing on each other’s transatlantic flights between London, Dublin, Shannon and the USA.
This means that Aer Lingus flights from Shannon to Boston and New York JFK and from Dublin to Boston, New York JFK, Washington Dulles, Chicago O’Hare, Orlando and San Francisco can be booked under a BA flight number on ba.com
Codeshares can be booked whether connecting from London or starting your journey in Dublin or Shannon.
The main benefit of this arrangement is that members of the British Airways Executive Club can earn Avios points and Executuve Club tier points in the same manner as a British Airways flight.
All passengers also benefit from US Customs & Immigration pre-clearance in Dublin and Shannon and connections are available from London Gatwick for those who would prefer to avoid London Heathrow.
Similarly, the Aer Lingus code has been placed on all BA transatlantic flights from London Heathrow and Gatwick, giving Aer Lingus passengers access to a more extensive route network.
It’s also worth noting that codesharing does not apply to BA routes to Canada and Central & South America.
Furthermore, a date has not yet been set for Aer Lingus to join the transatlantic joint-venture with American Airlines which is subject to commercial negotiation and regulatory approval.
Nor has a date been set for Aer Lingus to rejoin the Oneworld alliance.
