Thanks Tafflyer and FlightDetective

It’s a bit of a strange one. Seems that generally BA (on the app certainly and mobile website) are limiting options for flights from Dublin to JFK. They seem to be pushing EI from DUB to LHR over BA to LHR and not offering all the available flight combinations. I guess I’ll have to ring them and try book using specific flight numbers.

I agree it’s not worth saving €60 for a codeshare
