You should do the milk run that Widerøe does. Really nice scenery!
Try EGGD. Great for TUI flights including the Dreamliner, TC if you still want to use that livery, easyJet and Ryanair.
You could fly to both airports in Milan, Italy:
MXP and LIN
What is the milk run?
Basically a flight with many stops which delivers cargo and supplies to (mostly) rural towns.
I’ve found this little cute airport you may enjoy.
Honestly I recommend UIO or Quito. Super cool place, unique approach.
As for Europe, I would recommend Madeira and Spain and that area.
Just search up what is a milk run in aviation.
kbzn from boston
Does Gibraltar Count? If so, fly there.
What is the route of the milk run?
PHDH in Hawaii
Use this for some more suggestions:
I would suggest Gibraltar it is a really cool airport and basically no is ever there
LOWI Innsbruck is alway a beautiful approach between the mountains much similar to NZQN like @Etrain brought up
Fly to Belgrade or Niš!
Stuttgart or Ljubljana?
Anchorage, Cordova, Yakutat, Juneau, Sitka, Petersburg, Wrangell, Ketchikan, Seattle.
All great airports, and the airports served in the famous Alaska Airlines Milk-Run.
Dublin that’s a really good airport
