I have just purchased UT2 after using another product and one issue I have to bring up is a problem I have found with multiple short hop flights with a single aircraft. I am running local flights in the UK and trying to simulate a single aircraft returning to the base airport before flying out on its next flight. The problems lies in the fact that UT2 sees them all as separate aircraft and fills the airport with all these flights waiting for their turn. I haven't found a way to get around this and from my point of view I would probably be better off with FST. Other than that it works vey well.
