Just as many executive jet movements at Luton as ever. There are operators that seem to switch between the London "biz fields" from time to time but the overall position of exec jets at Luton shows no signs of tailing off.
I suspect that part of the increase in movements at Farnborough results from the large increase in based aircraft there - TAG Aviation in particular have added a significant number of aircraft over the past 12 months.
In any case, they will all come to Luton when they can't get weekend/bank holiday slots at Farnborough and the slots run out towards the end of the year at Northolt!!!!
