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 255 routes we track, it ranks 114 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.
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.
