United Airlines: Electric Aircraft Set to Take Flight by 2026

  • Electric aircraft set to take flight under new agreements with United Airlines Ventures, Breakthrough Energy Ventures, Mesa Airlines and Heart Aerospace.
  • United Airlines signs agreement to acquire 100 of Heart Aerospace’s ES-19 aircraft, a 19-seat electric airliner that has the potential to decarbonize regional air travel.
  • United Express regional partner, Mesa Airlines, also signs agreement to acquire 100 of the electric aircraft.

United Airlines Ventures (UAV) announced today it, along with Breakthrough Energy Ventures (BEV) and Mesa Airlines, has invested in electric aircraft startup Heart Aerospace. Heart Aerospace is developing the ES-19, a 19-seat electric aircraft that has the potential to fly customers up to 250 miles before the end of this decade. In addition to UAV’s investment, United Airlines has conditionally agreed to purchase 100 ES-19 aircraft, once the aircraft meet United’s safety, business and operating requirements. Mesa Airlines, United’s key strategic partner in bringing electric aircraft into commercial service, has also agreed to add 100 ES-19 aircraft to its fleet, subject to similar requirements.

UAV is building a portfolio of companies that focus on innovative sustainability concepts and create the technologies and products necessary to build a carbon-neutral airline and reach United’s net-zero greenhouse gas emissions goals. With this new agreement, United is deepening its bold commitment to reduce its greenhouse gas emissions 100% by 2050 without relying on traditional carbon offsets, as well as enabling the growth of Heart Aerospace and participating in the development of aircraft that will reduce greenhouse gas emissions from flying.

“Breakthrough Energy Ventures is the leading voice of investors who are supporting clean-energy technology creation. We share their view that we have to build companies who have real potential to change how industries operate and, in our case, that means investing in companies like Heart Aerospace who are developing a viable electric airliner,” said Michael Leskinen, United’s Vice President Corp Development & Investor Relations, as well as UAV’s President. “We recognize that customers want even more ownership of their own carbon emissions footprint. We’re proud to partner with Mesa Air Group to bring electric aircraft to our customers earlier than any other US airliner.  Mesa’s long serving CEO, Jonathan Ornstein has shown visionary leadership in the field of electric-powered flight.”

UAV and BEV are among the first investors in Heart Aerospace, demonstrating confidence in Heart’s design and creating potential for Heart to fast track the ES-19 introduction to market as early as 2026.


“Aviation is such a critical piece of our global economy. At the same time, it’s a major source of carbon emissions and one of the most difficult sectors to decarbonize,” said Carmichael Roberts, Breakthrough Energy Ventures. “We believe electric aircraft can be transformational in reducing the emissions of the industry, and enable low cost, quiet and clean regional travel on a broad scale. Heart’s visionary team is developing an aircraft around its proprietary electric motor technology that will allow airlines to operate at a fraction of the cost of today and has the potential to change the way we fly.”
