Although the Federal Aviation Administration (FAA) has already agreed with telecommunications companies Verizon and AT& T agreed to postpone the use of C frequency band until After January 19, and will not ask telecommunication companies to postpone the service for the time being. But airlines are clearly not happy.

Foreign media reported that some foreign airlines said they would suspend some flights after domestic airlines in the United States protested against the introduction of C-band in 5G networks.

The spectrum battle between U.S. telecom and airlines has been going on for a long time,Airlines argue that the C-band of 5G signals could interfere with cockpit security and automation systems, making it impossible to determine the plane's altitude and atmospheric pressure, forcing a large number of flights to be delayed, diverted or cancelled.

In a letter to the FEDERAL Aviation Administration and Federal Communications Commission on Monday, ceos of American Airlines, Delta Air Lines and United Continental Airlines said they would cancel a large number of flights if carriers start using the C-band on January 19.

Eventually, after negotiations, Verizon and AT& T-band agreed to delay the use of C-band around some airports.

But even so,Some foreign airlines, including Emirates, All Nippon Airways and Japan Airlines, still said they would cancel some flights to the United States.

Emirates said some of its flights to Boston, Chicago, Dallas, Fort Worth, Miami, Orlando, San Francisco, Newark and Seattle were affected. Flights to Los Angeles, New York's John F. Kennedy International Airport and Washington, D.C., will operate as scheduled.
