how fast does a boeing 747 go

A Boeing 747 typically cruises at about 570 mph (around 917 km/h), which is roughly Mach 0.85–0.86 at cruising altitude.

Quick Scoop

• Typical cruising speed: about 570 mph (917 km/h).

• Usual cruise Mach number: around Mach 0.85–0.86.

• Maximum cruise / top end: up to about 660 mph (around Mach 0.86–0.90, depending on variant and conditions).

• Takeoff speed: roughly 180–190 mph, much slower than cruise, because it’s limited by runway length and safety margins.

Why the Numbers Vary

• Different 747 versions (like the 747‑400 vs 747‑8) have slightly different optimal cruise speeds.

• Airlines often fly a bit slower than the absolute max cruise to save fuel while still staying on schedule.

• Weight, winds, and route all affect the exact speed on a given flight.

In everyday terms: if you’re on a Boeing 747, you’re usually slicing through the sky at close to 600 mph for most of the long-haul journey.

TL;DR: A Boeing 747 usually goes about 570 mph (917 km/h) at cruise, with a maximum cruising speed up to around 660 mph depending on model and conditions.
