Panetta's Commuting Tab: About $860,000 So Far It's turning out to be a costly commute home for Defense Secretary Leon Panetta. The Pentagon chief has traveled on military aircraft to his home in northern California more than two dozen times since he took the defense post in July - trips that have cost the government about $32,000 each. Panetta, in turn, has reimbursed the government about $630 per roundtrip for the personal flights, based on longstanding formulas dictated by federal policies. The totals detailed by defense officials lay out his reimbursements for the first time, showing that as of March 19, Panetta had written checks to the Treasury totaling about $17,000 for 27 roundtrip flights. The total cost to the Pentagon is as much as $860,000 based on average fuel and operating costs for his Air Force planes. As Pentagon chief, Panetta is required to travel on military planes because they have the secure communications equipment he needs to stay in contact with the president and other top civilian and military leaders. The amount he pays is calculated using what a full-fare coach trip would cost. According to the Pentagon, the actual costs are about $3,200 per flight hour to operate the small plane he usually uses for the 10-hour round trip. When he took the job, Panetta made it clear that he would continue to return home to his family on the weekends as he had done as CIA director for the previous two years and as a member of Congress from 1977-1993. The cost of the flights is a tiny fraction of the Pentagon's proposed $614 billion budget. But Panetta comes to the defense job at a particularly difficult financial time for the department. If Congress can't reach an agreement on savings or additional revenues elsewhere in the federal budget by next January, officials could be forced to cut nearly $1 trillion in defense spending over the next 10 years. When Panetta took the post, it was noted that he came with budget skills honed during his time as chairman of the House Budget Committee, head of the White House Office of Management and Budget and White House chief of staff for President Bill Clinton. "No one understands the budget pressures on the Pentagon better than Secretary Panetta, who is responsible for identifying nearly $1 billion per week in defense cuts - or roughly $140 million per day - over the next 10 years," Pentagon press secretary George Little said. As a required-use traveler, he must use government aircraft for all travel. Little said Panetta values his time with his wife and family and "spending time away from Washington, in fact, helps him focus on the job and recharge." White House national security spokesman Tommy Vietor added, "Secretary Panetta has done an exceptional job in both his role at the CIA and as secretary of defense. He has been on call 24 hours a day, seven days a week, and has always been reachable through secure channels whenever necessary, wherever he is. Panetta's two predecessors didn't make such frequent, long trips home. Robert Gates spent most weekends in the nation's capital but traveled occasionally to his family home in Washington state. Donald H. Rumsfeld also lived in the D.C. area but often spent weekends at his house in St. Michaels on Maryland's Eastern Shore. Panetta's wife, Sylvia, works full time at the Panetta Institute for Public Policy, which they established in Monterey, Calif., in 1997.
