American Airlines transported 8.4 million passengers between the United States and Europe in the year leading up to November 2024, according to data from the US Department of Transportation. This figure places American as the third-largest operator on these routes, following Delta Air Lines with 11.3 million passengers and United Airlines with 10.8 million.
The airline operated 51 routes during this period, achieving an average seat occupancy rate of 82%, slightly below the industry average. All transatlantic flights were conducted using widebody aircraft, a practice that continues into 2025.
Among American's European routes, seven had over 250,000 roundtrip passengers each. These routes all involved London's Heathrow Airport and benefited from American's partnership with British Airways through their transatlantic joint venture. These seven routes accounted for approximately 40% of American's European traffic.
