The authorities in the United States have tightened airline security procedures after the main suspect in last week's failed car bomb plot in New York was able to board a flight for Dubai.
Faisal Shahzad, 30, an American citizen of Pakistani origin, was arrested as the plane was about to take off.
In a move to stop known suspects from boarding planes, airlines must now check no-fly lists within two hours of being told of updates to watch-lists, the BBC reports.
Faisal Shahzad has admitted trying to detonate a car bomb in Times Square, having learnt how to make it in Pakistan, court papers say.
He faces terrorism and explosives charges, including attempting to use a weapon of mass destruction and transporting an explosive device with the intent to kill.
