The support section article about RWYs in PRG says that they would only add it once it actually exists in real life, so it’ll still be a long way, since its planned for the 2030s… (and my experience with major infrastructure projects here in Czechia leads me to believe that it might stretch into the 40s)
Btw I think both your post and my reply should go to PRG - Conversation, since this thread is for actual screenshots from the game, so I’d like to ask the mods (@carlsberg72 @ukplanespotter757) to please move this
