United Airlines announced plans to bring back supersonic travel 18 years after Concorde’s final flight.

The US airliner recently purchased 15 planes capable of travelling at twice the speed of modern airliners from Denver-based, Boom Supersonic.

Their Overture aircraft could potentially bring back the days of the 3.5 hour transatlantic journey via New York and London with planes able to fly at Mach 1.7 (1,300mph).

“United continues on its trajectory to build a more innovative, sustainable airline and today’s advancements in technology are making it more viable for that to include supersonic planes,” United CEO Scott Kirby said in a statement. “Boom’s vision for the future of commercial aviation, combined with the industry’s most robust route network in the world, will give business and leisure travelers access to a stellar flight experience.”

The jets are estimated to have 65 to 88 seats depending on an airline’s configuration, according to Boom said. If your wondering how much the flights will cost you’ll have to continue to wait but spokesperson Rachael Rivas said the plane is designed to have operating costs that are 75% lower than the Concorde.

The renaissance of supersonic travel is on hold for now until it “meets United’s demand safety, operating and sustainability requirements” with the two companies working together to meet those requirements.
