Fog rolled across Auckland Airport on Saturday morning and forced the cancellation of 15 domestic flights. Another 15 services ran late, meaning 30 domestic departures were disrupted in total before conditions improved. Dense morning fog is a familiar hazard at the airport, where low visibility can hold aircraft on the ground until the mist burns off. Travelers faced long waits at rebooking desks as airlines shuffled passengers onto later flights. The disruption rippled through the schedule for much of the day, since aircraft arriving late push delays further down the line. Airlines advised passengers to check their flight status before heading to the airport.
