British Prime Minister David Cameron surprised many this week by traveling to Washington for his first official White House visit since taking office on a commercial British Airways flight, instead of taking a dedicated plane, to save money. Now some Americans are wondering if U.S. officials could follow suit.

Having traveled around the world with four U.S. secretaries of state — Hillary Clinton, Condoleezza Rice, Colin Powell and Madeleine Albright — over the last decade, I can see how commercial flying would save the State Department millions of dollars a year. However, it would also guarantee a logistical nightmare.
