I think if FR reduce capacity at DUB and SNN it is because of the new tax. So if this is true there could be reduction at Cork, Kerry... too. If not then the tax is not the reason why FR cuts at DUB and SNN...in my opinion. Maybe the routes out of SNN and DUB aren't profitable any more and FR needs something to justify the cut backs?
EDIT: I don't hope that they will cut anything but if FR won't pay the tax they have to.
