Incheon airport's network fiasco raises questions over crisis readiness

Incheon International Airport’s latest check-in disruption has exposed its vulnerability to failures at external network providers, prompting calls for stronger contingency systems. The outage began around 4:30 a.m. Friday, when connectivity problems hit the global network of U.S.-based aviation communications provider ARINC, disrupting check-in operations at 13 airlines across both terminals. It delayed 38 flights and left around 1,200 passengers waiting at the airport, according to Incheon International Airport Corp. (IIAC). By the afternoon, ticketing operations at China Southern Airlines, China Eastern Airlines and Air China had nearly ground to a halt, forcing them to switch to manual procedures. The latest network fiasco clearly shows a structural vulnerability in airport operations. International airports and airlines rely on global IT providers to exchange passenger and reservation information, coordinate check-in procedures and issue boarding passes. Such platforms allow carriers to operate across multiple airports without building entirely separate systems at each location. Ho
