The airline Diamond Sky is flying scheduled flights between Pärnu (EEPU), Ruhnu (EERU) and Kuressaare (EEKE) from October to April with a Britten Norman Islander BN-2 aircraft. Now all three airports are available here on fsaddons.fi! EEKE is made for MSFS2020 but works perfectly also in MSFS2024. EEPU and EERU are MSFS2024 native, so they do not work in MSFS2020. Unfortunately MSFS2024 made stuff can not be converted back to MSFS2020 without starting from scratch, so there will be no MSFS2020 versions of EEPU and EERU. Enjoy!
