Irish site TRAVELExtra have reported that Aer Lingus and British Airways have extended their codeshare agreement. The airlines are already codeshare partners on routes between Ireland and the United Kingdom and this new agreement covers routes between Ireland and Europe. Both airlines are owned by International Airlines Group (IAG) which means this extension is no surprise. It is expected that Aer Lingus will join the transatlantic joint venture in due course.

Codeshare Beware

On the face of it this is great news! It means you can book Aer Lingus flights on the British Airways web site and earn all your normal Avios miles without having to worry about fare class. I was kicking myself for not checking the British Airways web site for a recent booking from Dublin to Glasgow. Upon investigation though, I made the right choice.

Aer Lingus flights between Dublin and Glasgow out on 8 November and back on 9 November price up as follows.

EI8Nov
EI9Nov

This is a total of €54.98 in the lowest fare class or €106.96 on a Plus Fare which gives you seat selection and a 20kg hold bag. British Airways on the other hand price the exact same flights as follows.

BA89Nov

€181.00 for exactly the same flights! They do include a bag and seat selection but even so it is almost €75.00 more for absolutely no reason whatsoever.

Overall Thoughts

The integration of Aer Lingus into IAG joining Iberia, British Airways and Vueling is a good thing. It will provide many more options for frequent flyers to earn points on more flights and that is excellent. Anyone who finds a suitable Aer Lingus flight on the British Airways web site should check with Aer Lingus directly. There could be a substantial cost saving on the ticket. I understand the price difference is due to which fare classes are available for the codeshare however it certainly pays to be informed. Thanks for reading and if you have any comments or questions, please let me know.
