Widespread IT outage halts Southwest Airlines flights, causing major travel disruptions.

Southwest Airlines experienced a temporary grounding of flights due to a widespread IT outage affecting its vendor Amadeus, which handles booking, check-in, and baggage systems. The outage caused long lines, check-in failures, and app issues across multiple states, disrupting travel plans for many passengers. The problem began around 8 a.m. ET and peaked near 8:50 a.m., with services gradually restoring afterward. Southwest apologized for the inconvenience and emphasized customer and employee safety as a priority. Similar outages recently affected other major airlines like United and Delta, highlighting vulnerabilities in airline IT infrastructure.

Southwest Airlines faced significant disruptions due to an IT outage, which may be reflected in its stock performance. On Pluang, Southwest Airlines (LUV) trades at USD 41.32 with a slight 1-day decline of 0.10% as of Oct 10, 2026 00:51 WIB. Meanwhile, other major carriers also show mixed movements: United Airlines (UAL) is down 1.35% at USD 105.99, and Delta Air Lines (DAL) is priced at USD 81.22, down 1.12%.
