Looking at the Summer timetable it's really not pretty
4 per day weekday flights remain though the early morning DUB departure has now slipped back to 0745 which doesn't get into LHR until 0900 .. not really that competitive for ex DUB business traffic (early morning LHR departure remains at 0700) .. also some bizarrely long turnarounds in Dublin can hardly help with them making any money from having expensive aircraft sitting on the ground (shortest turnaround in DUB is 75mins and the longest is 2 1/4 hrs which seems bizarre to say the least - it's like they're not even trying )
On a Saturday there's now only 2 flights
On a Sunday there's bizarrely 5 flights LHR-DUB and only 3 back DUB-LHR .. suspect that 3 is the correct figure and then the curse of bizarre BMI scheduling strikes again as there's one flight in the morning and two afternoon flights within just over an hour of eachother mid afternoon ... sensible spaced out scheduling not!
So despite the glimmer of hope that reintroducing the early DUB-LHR flight showed last autumn it looks as though death by a thousand bizarre schedule cuts is proceeding on the DUB route
