Aer Lingus user accounts deleted this year?

[patfert1]

I didn't fly with Aer Lingus since December. When I went to do a checkin today for a flight booked on 1st March, I was unable to login. A "reset password" email failed to arrive, twice. After all the usual troubleshooting, I created a new login. It seems my old account had disappeared, since it allowed me to create a new account with the same email address I used previously.

According to Google AI, "Aer Lingus recently restricted new AerClub account registrations and experienced issues with user accounts due to a transition to a new third-party vendor in early 2026."

Did Aer Lingus actually delete lots of accounts and was it deliberate or an accident?

Have you ever had an Aerclub account?

Aer Lingus are owned by British Airways (IAG own them but BA shareholders the majority owners of IAG) and have migrated to the BA rewards system. That's a good thing since the BA system is much better.

Have you ever had an Aerclub account?

I checked back through my email and see a message from August 2025 stating that the "Basic Profile Accounts" would no longer be supported after 31 August, and before then I should register for AerClub through my Basic Profile Account. I suppose that would have migrated my data over, and after August it was then too late.

Ok, this is the explanation. Howevr it strikes me as pretty poor sense from a business marketing point of view to give customers just a few weeks (during the peak holiday season too) to migrate over, and the action has to be manually done by the customer, otherwise in a sense the airline "loses the customer". I worked with travel companies and loyalty programs in the past, and when there were such technology changes, a critical part of the project was always to automatically migrate customers to the new program.

Data protection now means they can't transfer the data to a new processor without permission. Some deal with that through the initial terms and conditions, but if they don't or you want to alter the purposes you're using the data for you need permission.

The lack of notice is unusual alright, I wonder did they give frequent flyers more time?
