In this episode, we speak with Luke Farajallah, CEO of Loganair, UK's largest regional airline that operates the world's shortest commercial flight and the only airline globally that lands commercially on a beach.

Farajallah discusses:

1. Loganair's unique "fishing in a big pond" approach to sustainable aviation, investing simultaneously in SAF, hybrid-electric aircraft with Heart Aerospace, and hydrogen propulsion with ZeroAvia rather than betting on a single technology.
2. Why regional airlines are better positioned than major carriers to pioneer sustainable aviation, given their shorter routes, smaller aircraft, and wider technology options beyond expensive, imported sustainable aviation fuel.
3. The company's mandatory £1 carbon offset programme included in every ticket, funding local environmental projects across Scotland through their Green Skies initiative, achieving near-zero customer resistance.
4. Strategic partnerships, including equipping Embraer aircraft with 130kg water vapour sensors for the UK Met Office to study contrail environmental impacts, and plans for the world's first hydrogen-powered commercial flight from Orkney.

As a leader who transformed Loganair's operational performance from 22nd to 2nd place in European rankings in just 12 months, Farajallah brings a results-driven approach to balancing commercial viability with environmental responsibility whilst serving communities that depend entirely on aviation connectivity.
