The Trump administration is promising to fix the nationwide shortage of air traffic controllers after recent control tower troubles on the East Coast and a string of crashes this year.

Travelers in Houston are feeling the ripple effects of significant delays at Newark Liberty International Airport (EWR), a major hub for United Airlines. With many Houstonians relying on flights to and from George Bush Intercontinental Airport (IAH) that connect through Newark, these disruptions could impact summer travel plans.

Federal investigators say an air traffic controller cleared one plane to land and another to take off from the same runway in Florida last month.
