The Al Thanis have always been a pain.
Back in the sixties and seventies they would order a scheduled service on a BAC1-11, F27 and once on a VC10, to be emptied so that the 'royal' family could go falconing, shopping or whatever.
They regarded Gulf Aviation as their personal possession.
(The fact that they sit on a natural gas field that is said to last until the year 2500 may have something to do with this!).
