Business travelers may find themselves facing long delays now that furloughs have kicked in for 47,000 Federal Aviation Administration workers on Sunday night,CNNMoney reported.


Specifically, 10 percent of the country's 1,500 air traffic controllers now will be forced to take unpaid time off each day, which could cause problems at some of the nation's larger airports including those in the New York area, Los Angeles, Dallas-Ft. Worth and Las Vegas.


Those heading to New York's LaGuardia Airport were facing two hour delays on Tuesday. And some airlines, including US Airways, JetBlue and Delta, canceled flights on Monday because of cutbacks, the New York Times reported.


The Federal Aviation Administration (FAA) reported that there were 1,200 delays on Monday specifically tied to fewer air traffic controllers at work and another 400 delays due to furloughs on Sunday.


Trade group Global Business Travel Association wrote to FAA Administrator Michael Huerta expressing its "significant concerns" about the potential delays for business travelers, The Wall Street Journal reported. "We are very much alarmed by the list of airports and the expected delays," said the association.
