United Airlines aims to bring back supersonic travel before the decade is over with a plane that has yet to be built.

The airline said Thursday that it plans to buy 15 jets from Boom Supersonic with an option for 35 more once the start-up company designs a plane that flies faster than the speed of sound while meeting safety and environmental standards.

United declined to discuss terms of the deal, including how much cash it will put into the deal up front.

It has been nearly two decades since the last flight of the supersonic Concorde, which British Airways and Air France began using in 1976 to zip passengers in luxury across the Atlantic. The last one was retired in 2003, three years after an Air France Concorde crashed into a hotel shortly after takeoff from Paris, killing everyone on board and four people on the ground.

Several companies are working to come up with new supersonic jets that would be more economical on fuel — and create fewer climate-changing emissions — than the Concorde.

Boom is working to develop a plane it calls Overture, which it says will be the first supersonic airliner to fly on so-called sustainable fuel.

The Denver company said the planes will be capable of speeds up to 1.7 times the speed of sound, or about 1,300 mph. That is slower than the Concorde but much faster than current airliners, which generally have cruising speed around or slightly above 500 mph.

United said flights between London and the New York area would be just three and a half hours, and Tokyo would be only six hours from San Francisco.

Boom hopes to test fly a plane by the middle of this decade and be carrying airline passengers in 2029.

United Airlines CEO Scott Kirby said technological advances make it more viable for the airline to include supersonic planes in its fleet.

Al Sharpton to lead pro-DEI march through Wall Street
The Rev. Al Sharpton is set to lead a protest march on Wall Street to urge corporate America to resist the Trump administration’s campaign to roll back diversity, equity and inclusion initiatives. The New York civil rights leader will join clergy, labor and community leaders Thursday in a demonstration through Manhattan’s Financial District that’s timed with the anniversary of the Civil Rights-era March on Washington in 1963. Sharpton called DEI the “civil rights fight of our generation." He and other Black leaders have called for boycotting American retailers that scaled backed policies and programs aimed at bolstering diversity and reducing discrimination in their ranks.
A US tariff exemption for small orders ends Friday. It’s a big deal.
Low-value imports are losing their duty-free status in the U.S. this week as part of President Donald Trump's agenda for making the nation less dependent on foreign goods. A widely used customs exemption for international shipments worth $800 or less is set to end starting on Friday. Trump already ended the “de minimis” rule for inexpensive items sent from China and Hong Kong, but having to pay import taxes on small parcels from everywhere else likely will be a big change for some small businesses and online shoppers. Purchases that previously entered the U.S. without needing to clear customs will be subject to the origin country’s tariff rate, which can range from 10% to 50%.
Southwest Airlines’ new policy will affect plus-size travelers. Here’s how
Southwest Airlines will soon require plus-size travelers to pay for an extra seat in advance if they can't fit within the armrests of one seat. This change is part of several updates the airline is making. The new rule starts on Jan. 27, the same day Southwest begins assigning seats. Currently, plus-size passengers can pay for an extra seat in advance and later get a refund, or request a free extra seat at the airport. Under the new policy, refunds are still possible but not guaranteed. Southwest said in a statement it is updating policies to prepare for assigned seating next year.
