IOM Spotter - I think we'll just have to agree to differ on this one. Whatever the precise timing, the reduction in capacity is only around 8% against what was offered in the summer months. I’d suggest this is not a big deal at an airport which still has a highly seasonal trade.
There are not "Gonna be a lot of parked up aircraft" (except perhaps when we have a dusting of snow).There maybe one for a few hours on some quieter days of the week. Your initial post seemed to be written in a sensationalist style to convey, deliberately or otherwise, the impression that IOM is going to turn into some sort of aviation graveyard, which is simply not the case.
Of course all those cheap Easyjet seats are going to cause BE and others to take stock of overall capacity over the whole winter – that just looks like prudent business to me.
