If you’re looking for short hops, I’ve got some flight plans for you
44 airports in 6 hours. Avg 8 minutes per flight. Next one has 54 airports. The UK has airfields littered all over the place. Take off and landing are the best parts next to sight seeing.
I’m making less stops now since I’m re-creating my flight plans after flying them (following my nose to the next nearest airport in the approximate direction I want to go) I write down each stop then add them later to make a map of how I went. However the game insists on inserting the next stop in a illogical manner instead of simply adding it at the end. Re-organizing 54 stops with a text editor was not fun.
