US Department of Transportation's in-house watchdog stated (12-May-2011) it isn't clear why air traffic controller errors increased by 53% in 2010 (Associated Press, 12-May-2011). Inspector General Calvin Scovel told a Senate Appropriations subcommittee the Federal Aviation Administration has placed large numbers of inexperienced controllers at some of the nation's most complex air traffic facilities. Mr Scovel stated that as of 25-Mar-2011, 25% of controllers were in training compared with 15% in 2004. The agency plans to hire 11,000 new controllers by 2019.

Emirates has multiple reasons for cutting back on US capacity
As the most conspicuous and largest, Emirates Airline often takes on its shoulders the increasingly difficult task of defending Gulf aviation. Emirates often single handedly represents the Gulf and "Middle East Big 3", in much the same way as Dubai carries regional geopolitics.
Just as there are significant differences between the Big 3 US airlines who have strenuously opposed the Gulf carriers in the US market, so Emirates is fundamentally different from its peers: it is longer established, has a larger home market and has had a more commercial mandate from the beginning.
Yet Emirates must compete in a market where many others would like a piece of that market. Just as Dubai Inc modelled itself in many ways on Singapore Inc, there are many who would follow the same trail. This does not lead to steady market conditions.
Certainly the policies of US President Trump have hurt aviation and tourism. But Emirates' announcement of a 19% reduction in services to the United States is less about US policies and more about the nature of the market forces that started before Trump was even a serious Presidential contender.
