American Airlines expects to welcome more than 7.8 million customers — a record for the airline — during the Thanksgiving travel period, which runs from Nov. 16 to Nov. 28. This holiday travel period will be the airline’s busiest ever and comes as American has been running the most reliable operation of any U.S. network carrier for the past 14 months. That includes the summer 2023 travel period, when American led its major network competitors in completion factor and on-time departures.
