It has to be Luton. Stansted is being worked on by another very good developer in Gaya so makes no sense having two fantastic devs working on the same airport. The UK 2000 rendition of Luton is dreadful and in all likely wont be updated. Lutons such an important UK airport it links to all the quirky airports across Europe in places like Poland, Romania and the Balkans, massive base for both Wizz and EasyJet. Please we need a Luton in MSFS with your talents!
