Calgary travellers were affected by a nationwide US flight ground stop on Friday evening, per Calgary Herald reports. The FAA ordered the advisory 111 at 20:53 UTC, grounding all departures and holding inbound international flights case by case.

The outage, caused by air traffic control communications issues rather than a cyberattack, lasted until 01:28 UTC on 14 Nov, with nearly 5,000 flights cancelled, reports Business Insider. Canadian airports including Toronto and Montreal also grounded flights during the event.

Flight delays and cancellations continued into the early hours of 14 Nov, as international departures resumed from US hubs like JFK and LAX. Calgary residents were among those stranded or delayed, per CBC News.

The disruption rippled globally, with UK, UAE, and Canadian media reporting on the impact. Canada's Nav Canada confirmed its systems remained operational amid the US outage, as reported by Medicine Hat News.
