What is Flight Chain
A daily simulation game built on real Japanese domestic flight data: chain tomorrow's flights together to maximise total distance. Build a flight plan each day, then your score settles on the next day's actual operating results.
How to Play Flight Chain
1. Pick your origin
Choose your starting airport from the nationwide list. Including the daily bonus airport anywhere in your route multiplies your score.
2. Chain connections
Pick flights departing from your current location. Layovers must be at least 20 minutes.
3. Lock in before the deadline
Lock your flight plan by 23:59. After locking you can't edit. Until then, edit freely.
4. Score settles tomorrow
Actual flight results (on-time / delayed / cancelled) determine your score. Missing a connection forfeits all subsequent legs.
Rules
- Sum the great-circle distance (km) of successful legs — measured straight-line between airports, not the actual flown route
- Including the bonus airport anywhere in your route multiplies the total
- If the previous flight's actual arrival leaves less than 20 minutes before the next flight's actual departure, the rest of the chain is missed
- If a flight is cancelled, all subsequent legs fail
- Diverted flights still earn distance — measured straight-line to the actual landing airport — but break the chain for subsequent legs
