Paarmo The data is freely available from CAA :-
UK Airport Provisional Statistics: 2009 - 05 | Data | Economic Regulation
It would be unusual if the data recorded was not to become final.
Few observations :- DTV is "year on year" ranked at #29 in the UK, but based on May's performance then position drops to #32 - basically approaching the worst in the UK!, i.e it could not really get much worse. In reality the position may improve slightly over summer if more IT pax than say NQY but basically it's dire !
As for Peel as a whole then from a trading perspective they can not be pleased with their investment in airports, apart from previously noted large balance sheet losses posted in recent years then things don't look too good when their flagship LPL is down to #12, with DCS at #22. Cost cut's on the way?
