As a regular SLF on ORK/DUB-LHR, the last thing the LHR routes need is an equipment downgrade in my view. Throughout the recessions on both sides of the Irish Sea, it's been a pleasent surprise to see how resilient the LF's have been on the LHR services, no matter what the time of day or day of the week.
In my view ORK-LHR is crying out for an A321 or the 5th daily flight back!
