In-Depth Analysis
San Francisco International Airport (SFO), a key transpacific gateway, experienced a major operational breakdown on May 11, 2026. Carriers like Frontier, United, and American Airlines struggled with suspensions and delays, impacting thousands of travelers. The disruptions rippled through the International Terminal, affecting major cities such as Paris, Beijing, Hong Kong, and Dallas.
While SFO grappled with these issues, the US aviation system showed signs of recovery. On May 8, 2026, disruptions were concentrated at secondary and regional airports like San Diego (194 disruptions), Salt Lake City (76), and Jacksonville (52), rather than major national hubs. This shift indicates a move towards stabilization, supported by the clearing of Spirit Airlines’ ghost flights and the absorption of rescue fare passengers.
However, two major countdowns loom: the FAA’s O’Hare summer flight cap on May 17 and Memorial Day weekend on May 23. The O’Hare cap will reduce peak operations, potentially causing further schedule adjustments and transition risks. Memorial Day weekend, with approximately 45 million Americans traveling, will test the system’s capacity, especially with Spirit Airlines’ absence leading to higher fares and fuller flights.
San Diego International Airport (SAN) faced unique challenges due to its single-runway operation, leading to cascading delays. Salt Lake City International Airport (SLC) experienced disruptions due to late-season snowfall, impacting Delta’s Mountain West hub. Jacksonville International Airport (JAX) saw increased delays as passengers from the ceased Spirit Airlines migrated to other carriers.
