IB6403 distance and great-circle path
IB6403 covers 9,066 km, or 5,633 miles. That makes it an ultra-long-haul flight, near the limit of what most twinjets can fly non-stop. Of the 439 routes we track, it ranks 104 by distance.
The plane leaves Madrid heading 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 MAD-MEX route appears on a tracker map.
Why IB6403 block time differs from cruise time
The schedule allows 11.6 hours from gate to gate. That works out to about 783 km/h. An Airbus A350-900 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 high-altitude winds behave in our guide to turbulence and jet streams.
Can the Airbus A350-900 comfortably fly IB6403?
Not really. It uses about 60% of the Airbus A350-900's range. That leaves room for a full load of passengers and bags. The full numbers are on our aircraft page for the Airbus A350-900.
What to know about IB6403
- Time change: you land 7 hours behind the time you left. That is enough to cause jet lag. Here is how pilots handle it.
- High airport at the end: MEX sits 7,316 ft up, so the plane lands faster than it looks.
