Finnair has signed a so-called letter of interest with Swedish electric aircraft developer Heart Aerospace that could lead to the airline’s acquisition of as many as 20 of Heart’s 19-seat ES-19 model for use on short routes. According to Heart CEO Anders Forslund, 12 airlines have now signed letters of interest covering more than 300 prospective orders, with Finnair being the most prominent to make a public commitment so far.

Heart Aerospace in September unveiled the electric propulsion system meant to power the ES-19. Scheduled for entry into service in third-quarter 2026, the airplane features four propellers powered by electric motors.
