It was a tough start to the week for many air travellers. Flight delays piled up all along the East Coast on Monday as thousands of air traffic controllers were forced to take an unpaid day off because of federal budget cuts.
Some flights into New York, Baltimore and Washington were delayed by more than two hours as the Federal Aviation Administration kept planes on the ground because there weren't enough controllers to monitor busy air corridors.
One out of every five flights at New York's LaGuardia International scheduled to take off before noon on Monday was delayed 15 minutes or more, according to flight tracking service FlightAware. Last Monday morning, just two per cent of LaGuardia's flights were delayed. The situation was similar at Washington's Reagan National Airport, in Newark, New Jersey, and in Philadelphia.
