Before that, the record for the fastest subsonic Atlantic crossing was held by Norwegian. It set its record in January 2018 with a Boeing 787 Dreamliner on flight DY7014 at a crossing time of five hours and 13 minutes.

The airline announced it scooped up 15 supersonic jets dubbed "Overture" from the Denver-based firm Boom Supersonic. The jets can reach a top speed of 1,300 MPH, or Mach 1.7 speeds. Mach 1 is the speed of sound.

And, for the environmentally friendly . United says its Overture will be the first large commercial aircraft to be net-zero carbon from the get-go. It's also slated to be optimized to run on 100% sustainable aviation fuel.

Boom has not yet tested a supersonic jet in flight, although in October 2020 the company promised it would fly its test XB-1 jet sometime in 2021. Once developed, Overture will send passengers from Paris to Montreal in only 3 hours and 45 minutes, about half the current metric of 7 hours and 15 minutes, according to Boom.

"Learning from Concorde and building upon its foundation, we defined three core principles to guide every strategic decision and facet of the organization — speed, safety and sustainability," Scholl added. "For us, these principles enable supersonic flight that is affordable for passengers, profitable for airlines and capable of reaching economies of scale with tens of millions of passengers."
