If they are including all the handcrafted airports from the MSFS2020 Premium Deluxe plus all the handcrafted airports from the WU, SU, and CU releases, i count 169 from ([GUIDE] Asobo Handcrafted Airports | MSFS 2020)
Subtract the glider strips, that’s 154. Am i miscounting?
Hope to see an offical list soon.
