On the original subject of the post, I gather that Peel are in talks with several US airlines, particularly Continental.
Peel it seems have a firm belief in direct US sheduled flights to serve East of the Pennines and even 5th/6th freedom onto Eastern Europe!
I guess though that the success of Finningley may mean that Sheffield's airport becomes an industrial estate or business park - afterall, that's what Peel specialise in.
