SEA departure delays · SFO departure delays

GET /routes returns each SEA–SFO flight: airline, departure time, duration and the days it operates.
Field names match the live API. This flight only shows the shape. It is not a live result.
That URL still says YOUR_ACCESS_KEY.
A 7-day trial replaces it with a real key and returns each SEA–SFO flight in the JSON above.
After the trial, Starter is $24.99/mo.
