Not right now, no. I have a somewhat hard deadline for the preview game world in about three weeks, so my focus is 100% on that at the moment. Once that’s live, I will return my attention to the ORS-DS hybrid in general and bulk generation of travel requests in particular. As part of that, I will probably revisit the related flight instancing topics, depending on what’s next.
I see. I can’t shake the feeling that this is a symptom of a missing, better feature that should exist for this particular purpose. I know that many (if not all) players - myself if included if I actually get around to playing the game - basically open stations as a sort of “to-do list”. Which is a bit weird because just imagine a large network carrier in reality just sprinkling stations all over a continent, each with a clerk pushing pencils all day, waiting to do something someday 
Jokes aside, I figure that in travel lingo, a potential or actual place to fly to would be called a destination for strategic purposes, while a station is a very much operational concept that only becomes required once you actually open routes. Maybe we need that additional layer of abstraction to manage exactly that sort of thing…keeping track of potential places to fly to and evaluating their performance once you do.
