AS7 distance and great-circle path
AS7 covers 7,655 km, or 4,757 miles. That makes it a long-haul flight, a widebody route with a full night's flying time. Of the 439 routes we track, it ranks 147 by distance.
The plane leaves Seattle heading north-west. On the map above, the line looks curved. That is normal. The shortest path over a round planet never looks straight on a flat screen. Our guide explains how the SEA-NRT route appears on a tracker map.
Why AS7 block time differs from cruise time
The schedule allows 10.8 hours from gate to gate. That works out to about 707 km/h. A Boeing 787-9 cruises faster than that. The gap is taxi time, climbing, descending and holding.
Flying west, this route pushes against the wind. The trip back east is usually shorter, even though the distance is the same. See how timing changes the trip in our red-eye flight guide.
Can the Boeing 787-9 comfortably fly AS7?
Not at all. At roughly 55% of its range, this is an easy trip for a Boeing 787-9. The airline picked it for cabin size, not distance. The full numbers are on our aircraft page for the Boeing 787-9.
What to know about AS7
- Time change: you land 16 hours ahead of the time you left. That is enough to cause jet lag. Here is how pilots handle it.
- Crosses the date line: the calendar date changes while you are in the air.
