The CEO of United Airlines penned a letter to employees outlining what he thinks the Federal Aviation Administration needs to do to fix all the delays plaguing Newark Liberty International Airport. The delays began last Monday when crews in the Philadelphia air traffic control facility that lines up flights into and out of Newark lost radar and communications with the planes for at least 30 seconds.

United Airlines is letting customers change flights for free as flight delays and cancellations continue to grow at Newark Liberty International Airport in New Jersey.

By mid-day on Monday, more than 150 flights were canceled and more than 250 flights were delayed at Newark Liberty International Airport.
