Seoul-Los Angeles-Seoul
After returning to Seoul, the Los Angeles Times reported that the flight attendant may have operated two additional flights between the South Korean capital and Los Angeles. The flights that were serviced by the flight attendant, KE17 and KE12, reportedly took place on February 19 and 20, respectively, with a one-night layover in Los Angeles, the LA Times reported.
Korean Air operates multiple daily flights between Seoul and Los Angeles with some of its largest aircraft including the Airbus A380 and a Boeing 747-8i. The flights that the flight attendant reportedly worked were operated by the Airbus A380, the world's largest passenger jet seating over 400 passengers in Korean Air's configuration.
