Stansted does have quite a few business jets each day. However, they are generally the bigger ones such as 747s, 767s and other assorted mediums plus the usual Gulfstreams and Globals. I guess 1 747 equals about 10 Gulfstreams in landing and parking fees! But it is quite busy during the off-peak times with operators using Harrods, Fayair and Inflight.
