American Airlines and Boom Supersonic announced the airline’s agreement to purchase up to 20 Overture aircraft, with an option for an additional 40. American has paid a nonrefundable deposit on the initial 20 aircraft. Overture is expected to carry passengers at twice the speed of today’s fastest commercial aircraft. Boom Supersonic’s Overture, according to an announcement, would introduce an important new speed advantage to American’s fleet. Under the terms of the agreement, Boom must meet industry-standard operating, performance and safety requirements as well as American’s other customary conditions before delivery of any Overtures. Derek Kerr, American’s CFO, said that looking to the future, supersonic travel will be an important part of the carrier’s ability to deliver for its customers. Blake Scholl, CEO of Boom, said, “We believe Overture can help American deepen its competitive advantage on network, loyalty and overall airline preference through the paradigm-changing benefits of cutting travel times in half.” In July, Boom revealed the final production design of Overture, which is slated to roll out in 2025 and carry its first passengers by 2029. Overture is being designed to carry 65 to 80 passengers at Mach 1.7 over water — or twice the speed of today’s fastest commercial aircraft — with a range of 4,250 nautical miles. Optimized for speed, safety and sustainability, Overture is also being designed to fly more than 600 routes around the world in as little as half the time. Flying from Miami to London in just under five hours and Los Angeles to Honolulu in three hours are among the many possibilities.
