I was listening to an interview with the former president on National Public Radio yesterday, and it was interesting to hear him discuss his annual family Christmastime vacation. He says he books flights for his 23 family members using Frequent Flyer miles he accrues on all his flying during the year. Claims to book in coach, but will often get upgraded if there is room. He also said he likes to go throughout the plane and greet his fellow passengers before they take off. Noticed that since 9/11, when he does this there seems to be much more applause, and has determined that this is not because people are happy to meet him, but rather due to the Secret Service he brings on board.
