Teesside International Airport — Darlington, Durham, United Kingdom

Teesside International Airport (MME), located between Darlington and Middlesbrough in County Durham, England, serves the industrial Teesside region of northeast England. Formerly known as Durham Tees Valley Airport, MME underwent a high-profile renationalization by regional authorities in 2019 after years of declining traffic and near closure, followed by rebranding and renewed investment aimed at revitalizing services. The airport handles a mix of scheduled passenger flights, private and business aviation, and cargo operations, and it has also become associated with a growing offshore wind and green energy business park development on its grounds. MME's history includes wartime use as RAF Middleton St George, and it retains links to the region's aviation heritage through a nearby aircraft museum.
