US: Flight disruptions impacting Frontier Airlines, possibly other airlines, nationwide the evening of July 18 due to software issues

Flight disruptions likely for Frontier Airlines, possibly other airlines, across the US as of the evening of July 18 due to software issue.

Warning

Flight disruptions, including delays and cancellations, are likely for Frontier Airlines (F9) at airports across the US due to a software malfunction impacting booking and check-in systems. Local sources suggest the issue may also be affecting other airlines. Reports indicate significant flight disruptions at Denver (DEN) and Phoenix (PHX) international airports due to the outage. The Federal Aviation Administration (FAA) has announced a ground-stop order for Frontier.

Frontier flight disruptions are likely across the US in the coming hours. Similar disruptions are possible with other US-based carriers. Residual flight disruptions may occur through at least July 19 as airlines work to clear passenger backlogs.

Reconfirm flight schedules through at least July 19. Arrive at the airport well in advance of scheduled departure times; long lines are likely at curbside and terminal check-in counters until normal network operations resume. Do not check out of accommodations until onward travel is confirmed.
