Kiev...Hopefully taken up as a destination in 2021 by SkyUp Airlines who have received Ukrainian Government permit to fly Kiev-STN 3pw.
Podgorica...Ironically RYR threatened legal action against the state of Montenegro who were seeking to bail out Montenegro Airlines subsequently shutting down.
dj6... Do you post/research any other RYR destination closures from a myriad number of bases other than at the largest STN ?
