Delta Air Lines passengers faced a difficult overnight ordeal when two international flights were diverted to Montgomery Regional Airport due to severe thunderstorms impacting Atlanta. Passengers were stranded on board for nearly seven hours due to customs restrictions, as Montgomery lacks 24-hour customs facilities. Flight 599 from Mexico City and Flight 1828 from Los Cabos landed around 10:20 p.m. and 10:30 p.m., respectively, and disembarkation only occurred around 5 a.m. Delta has apologized, acknowledging they fell short of service standards and is offering refunds to affected passengers. The diversion was complicated by weather at their preferred backup airport in Birmingham.
