US airlines have lobbied to separate air traffic control from the FAA for two decades and Trump's budget plan released earlier this year called for the changes, placing air traffic operations under an "independent, non-governmental organization". The FAA would still have some oversight capacity, but the major airlines would govern this corporation.

Trump says the airline industry in America still relies on radar and ground control tracking systems, when nearly all of us have GPS enabled devices in our pockets.
"But after billions and billions of tax dollars spent and the many years of delays, we're still stuck with an ancient, broken, antiquated, frightful system that doesn't work".
