How do I search for and book Aer Lingus reward seats?

[Dawn]

I wanted to search for Aer Lingus reward seats to maybe use my 2-4-1 that I have. How do I go about this? Do I search on BA, or do I search on Aer Lingus? Thank you!

If you are using BA avios and a BA 2-4-1 then you search using BA.

But note EI relesses very limited business class rewards compared to BA

As you might expect, there are various articles on here, e.g.

The BA website seems to have some issues showing EI flights. E.g. I want to fly DUB-JFK (in economy) and I can’t get BA to show this option even though it can be booked on the EI site as a standalone and on the BA site if you start in LHR. It doesn’t show EWR flights either if you search NYC but does if you specify EWR. JFK doesn’t work inputting JFK or NYC. BA is the same price and gets free seat selection, where as booking through EI doesn’t (if anyone is wondering why not just book with EI!)

If the seats are available to BA, you should be able to book it by phone if not online.

Last year we stumbled upon flights from Man to MCO, direct but on other searches, if any J availability is found it’s often just 1 seat.
