Yea, with the maintence hangers at Dublin, they must be a good few maintence check flights operating in that area. I believe a few of Virgin's A340-600's get maintence at SR Technics at Dublin thus flying into there. Gulf Air also get maintence there and last year, I believe Gulf Air had a good few 767's grounded at Dublin. I believe some are still there.
I'm only just remembering this now however when I was at Dublin spotting at the end of 2008, when passing the maintence hangers, I think I might've seen the Star Alliance BMI A332 sitting outside the hangers along with one of the Gulf Air 767's.
I wonder if the A380 will ever find it's way into Dublin at some point.
