Aer Lingus & BA now codesharing on transatlantic routes

London Air Travel » Shannon

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

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.

British Airways and Aer Lingus have taken their first steps to greater collaboration now that the two airlines are under the umbrella of International Airlines Group.

The two airlines have historically codeshared on certain routes between Ireland and the UK, but BA codeshares on Aer Lingus operated flights have typically only been available when transferring onto a long-haul flight.

Aer Lingus routes between London Heathrow and Dublin, Shannon and Cork and London Gatwick and Dublin, Belfast City and Cork can now be booked via when travelling direct between the UK and Ireland from Wednesday 11 November 2015.

In addition, Aer Lingus routes between London Gatwick and Knock and London Heathrow and Belfast City can now be booked as codeshares through when travelling from Wednesday 11 November 2015.

BA is also applying its flight codes to Aer Lingus flights from UK regional airports, with Birmingham, Manchester and Liverpool being the first added.

A gentle reminder that when booking codeshares it is the operating airline’s procedures that apply regarding luggage and in-flight service. Also, Aer Lingus flights from London Heathrow depart from Terminal 2.

We should hear more in the coming weeks about greater co-operation between Aer Lingus, IAG and the Oneworld alliance specifically with regard to reciprocal frequent flyer recognition, codesharing and co-ordination of schedules.
