Nope. I think Privatair only use Boeing now - The A319s went to Etihad I believe.
Privatair do fly Amsterdam - Houston with the 737-700BBJ though (unless that's stopped)
inducedrag, depends. Some 737 BBJ fly long flights like the above. If were talking about the standard aircraft then BA Med used to fly 6-7 hours with A320/A321s.
