In the first line of the NOTAM it said something along the line that scheduled traffic would be given preference. Do the maths, one bizjet with 12 pax or one scheduled airliner with 130 pax.
Just because you arrive in a bizjet does not make you a VIP it just means you can afford it. I bet you there were more important people on the scheduled airliners. Lets stop talking about the bizjets as VIP as they are not unless carrying a head of state or the Blatter himself!
