Thanks for the speedy replies!
Prestwick vs Glasgow. Well, the reason I picked Prestwick was simply to be a little bit different. Glasgow is the airport to fly to if you're coming to Scotland, but if there is no good scenery then I will have to rethink that. I think Edinburgh has some good scenery about so thats an option for me.
I realise there are other VAs out there who do, or have done, these flights in the area but that's partly why I am looking for feedback. If it's mostly positive then that tells me it's worth pushing on. I still have months to go before I have to commit to anything yet.
Fleet. Glad you approve my choice. The reason I picked both Islander and Twotter is that the Islander is used in real life out of Connel to Coll/Tiree and Barra. I figured there was a reason, either a weight or cost limitation, especially as those routes are subsidised. I'll need to look into it, but if I can limit the types of aircraft then I will.
Expansion. I certainly have the motivation to keep going, and with a bit of clever branding I dont see any perceived limits of how far it can go. Except the obvious of course, if nobody wamts to fly with me.
About the control on vatsim being able to be gained with popularity, that's both inspiring that there is such an opportunity and a little bit frightening to be honest.
Thanks anyway, I'll go away, look at what needs changing and hopefully have a potentially working model by the end of it.
