5G Truce Expected to Avert Many—but Not All—Flight Disruptions

A truce reached this week in the standoff over new 5G service and aviation safety will forestall serious air travel disruptions, but remains likely to drive some cancellations, delays and diverted flights, aviation industry and government officials said.

An agreement by AT&T Inc. and Verizon Communications Inc. to delay their planned 5G rollouts until Jan. 19 will give the Federal Aviation Administration more time to address its safety concerns—and more narrowly tailor flight restrictions to protect aircraft from possible interference from the new wireless signals.
