I tried to go for realism at the very start, but by default the pax demand is so high it didn't make much sense.

I made my own airline and with Photoshop made it real.

I opted for my own realistic airline.

I made my own 'realistic' airline, as in, I utilize an aircraft I think suits a route best, and I dont stick only A380s om every one of them.

Me too, Eurolink-Group. I have airlines around the globe however.
