From the military side of the house, we would try to put general officers on our Citation Ultra's whenever possible, but we had more BE200s so 2 stars and below usually couldn't get a Jet. When we had a big move, such as a major trip to Normandy or Latina (Anzio) some generals that normally had a Citation reserved just for them and their staff had to slum it on the Beech.
On one such trip big trip, LTG Sanchez walked out of the terminal and went straight to one of the waitings citations. On this trip I believe we only had 3 Citations available and 4-6 King Airs flying. Well as he was trying to board he got the message, "Um, sorry sir, you're not flying on this today, that is your plane," and the pilot pointed to King Air. A few four letter words later LTG Sanchez stormed down the ramp and got on a King Air which he had to share with a couple other Generals (again, something he usually never had to do).
