State of play: American, Delta, United and Allegiant Airlines grounded flights early Friday morning due to communications issues, per an FAA alert.

• By the afternoon, the FAA said airlines were working toward resuming normal operations, but that ground stops and delays would continue intermittently at some airports.
• The agency also said the issue could continue to affect flights this weekend.

• Delta Air Lines said mid-morning it had resumed some of its flights but anticipated additional delays and cancellations throughout the day.
• As of Friday afternoon, there had been 847 delayed flights at ATL and 598 cancellations, per Flight Aware .
• It issued a travel waiver to all customers with flights departing Friday and said fare differences would be waived for passengers rebooking on or before July 24.

Zoom out: MARTA announced at 8:44am via X that its main website , as well as its websites for its smart card and real-time service information, were unavailable, but its bus, rail, and streetcar services are still operating.
