The undercover sky marshals aboard many commercial flights since the Sept. 11 terrorist attacks sometimes are stranded at the end of their workweek.
Sky marshals aren't guaranteed return trips when their workweek is done.
They must buy the tickets themselves or wait three days until their work resumes and they're placed on a flight taking them back home.
Rep. Bob Riley (R-Ala.) wants to see that air marshals get home for their days off. His amendment to the aviation security bill passed Thursday by the House would require airlines to pay for return tickets if the final flight of an air marshal's workweek leaves him or her away from home.
Riley's provision is not in the Senate version of the bill but he is optimistic that it will survive House-Senate negotiations.
