"by Robert Longley Updated September 04, 2017 The President of the United States and the Vice President are not the only non-military U.S. government officials who regularly fly on aircraft (Air Force One and Two) owned and operated by the U.S. government at the cost of taxpayers.

"By JAKE SHERMAN 10/30/2015 05:07 PM EDT House Speaker Paul Ryan will continue John Boehner's self-imposed prohibition on using government-chartered, private jets. As second in line to the presidency, the speaker of the House is allowed use of an Air Force jet to travel around the country. When Boehner (R-Ohio) took the speakership in 2011, he vowed to not use the jet. On Friday, Ryan's office told POLITICO that he would not use the jet, either. Boehner's prohibition did not extend to overseas travel. Nancy Pelosi caught flak when, as speaker, she flew home to San Francisco on a military airplane. That prompted Boehner's decision to impose the ban."

Nancy Pelosi caught flak when, as speaker, she flew home to San Francisco on a military airplane.
Pelosi didn't just fly home on a military airplane.
She did it almost every week and carried along a big group of people with her.
