American Airlines and Boom Supersonic today announced the airline’s agreement to purchase up to 20 Overture aircraft, with an option for an additional 40. American has paid a non-refundable deposit on the initial 20 aircraft.

Boom Supersonic’s Overture 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.

“Looking to the future, supersonic travel will be an important part of our ability to deliver for our customers,” said Derek Kerr, American’s Chief Financial Officer. “We are excited about how Boom will shape the future of travel both for our company and our customers.”

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 expected to carry passengers at twice the speed of today’s fastest commercial aircraft. It is 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. Flying from Miami to London in just under five hours and Los Angeles to Honolulu in three hours are among the many possibilities.

“We are proud to share our vision of a more connected and sustainable world with American Airlines,” said Blake Scholl, Founder and CEO of Boom. “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.”

Boom has yet to specify its engine on the supersonic Overture aircraft.
