Aboard Air Force One: Obama's Air Force One flight to Chicago and back Monday to cost $236,000

As President Barack Obama flies Monday to Chicago for a midday speech on health-care reform, the round trip on Air Force One will run about $236,000, according to government estimates of the operating costs for one of the top symbols, and perks, of the presidency.

But that does not include such expenses as Secret Service protection, motorcades and helicopter transports.
