American Airlines

American Airlines is the world's largest airline by fleet size and a founding member of the oneworld alliance, serving 350+ destinations across 60+ countries from nine US hubs including its giant Dallas/Fort Worth primary base — one of the world's busiest airport complexes — alongside Charlotte, Phoenix, Miami, Chicago O'Hare, Philadelphia, Los Angeles, New York-JFK, and Boston. American leads the industry in transatlantic seat capacity from the US, with dense service to London, Paris, Madrid, and beyond, complemented by the deepest Latin American network of any North American carrier. Its AAdvantage programme is one of the world's largest loyalty schemes, with co-branded Citi and Barclays credit cards, dynamic award pricing, and broad oneworld redemption options. A multi-year fleet renewal including Boeing 787-9s and Airbus A321XLRs will expand American's long-haul reach further into the 2030s.
