The aviation industry is facing enormous challenges, particularly in terms of its environmental footprint. Against this backdrop, Scottish company Ecojet Airlines, formerly known as Fresh Airlines, has announced big ambitions to reduce CO2 emissions from air travel. However, with the aim of establishing a sustainable airline, Ecojet has changed its launch plans and now plans to begin operations only in 2025. CEO Brent Smith announced that the company aims to "get everything right" before operating its first flights. Delayed launch Ecojet originally planned to start operations as early as early 2024, with the first services flying between Edinburgh and Southampton. However, these ambitious plans have been postponed due to internal considerations on how to properly implement the projects. Brent Smith commented on the reasons for the delay in an interview with *FlightGlobal*: "When it was first announced, it seemed doable, but our team decided to do extra work to make sure we were well prepared." The aviation authority has already applied for an Air Operator Certificate (AOC), which is an important step to start operations. The airline's IATA designation and call sign are also expected to be announced soon. Aircraft fleet and environmental technologies Ecojet Airlines plans to start with the ATR72-600, a modern turboprop aircraft suitable for short-haul flights. In addition, the company intends to use DHC-6 Twin Otters, which may later be converted to hydrogen-electric engines from ZeroAvia. However, Smith admitted that the second aircraft type is unlikely to be operational in the first one to two years. Dale Vince, co-owner of Ecojet and a well-known
