Then compare this to the time saved by utilising a private aircraft. The savings might surprise some people.
Exactly right. Time is money. Time spent sitting in lounges waiting for connecting flights is not taxpayer money spent well. I don’t understand the angst that people have towards politicians flying on charter/military flights. Especially for military flights, the flight hours are budgeted for anyway. If they weren’t flying a mission specific task like flying a politician around, they’d be flying a training sortie anyway. It just seems a case of whataboutism.
