(AP Photo/Lou Martins, File) The Transportation Department is ordering airlines to let passengers stuck in stranded airplanes to deplane after three hours. Transportation Secretary Ray LaHood announced the new three-hour limit today, along with other new passenger protections long sought by consumer advocates. From January to June this year, 613 planes were delayed on tarmacs for more than three hours, their passengers kept on board. Under the new rule, airlines must provide food and water for passengers within two hours of a plane being delayed on a tarmac and maintain operable lavatories. They must also provide medical attention when necessary. The new rule will go into effect in 120 days. (More Department of Transportation stories.) Report an error
