I'd like to see a breakdown of that bill. Private jets are much cheaper to operate than large commercial airliners, can't go any faster and don't charge per person.

Three days of European scheduled air travel at about £85 an hour, using average schedule trip rates, gives a maximum of £2040 per person per day.
A worst case total of £6120 per person, assuming the whole three days were spent in the air.

Oh yes, sod the people in Libya.
