Short regional hops land sooner, so you claim more often. That compounds cash, materials and airline XP — the three fuels of early growth. Long thin routes look impressive on the map but lock an aircraft for hours while fuel burn eats the margin.
Pick destinations inside comfortable range with a clear profit after fuel. Cabins fly full in Flyorian, so revenue scales with seats × distance; the skill is pairing enough seats with a distance you can turn around often.
Build a small rotation rather than a scatter of one-off sectors. Two or three favourite pairs from your home airport are easier to track, easier to refuel, and easier to compare. When one pair clearly pays better per hour of flying, shift more dispatches towards it and let the weaker pair rest.
Flights keep running on the server while you are away, so a short route also fits real life. Dispatch before you leave for work, come back, and claim what landed. Shorter sectors mean you are never waiting on a single flight for half a day, and a forgotten claim costs you less idle time than a forgotten long-haul.
