(CNN) - As the government tries to curb corporate excess of companies receiving federal bailout money, Treasury Secretary Timothy Geithner appears to be leading by example.

The man who was grilled by Congress last week over the AIG bonuses took the Delta shuttle from New York to Washington on Saturday, riding in the coach section. Asked why not first class, Geithner said he always rides coach, "never first class".
