The Boeing 747-8 Intercontinental, the most recent 747 passenger variant, has a typical cruise speed of Mach 0.86 while flying at an altitude of 35,000 feet, according to Boeing.

As result, the commercial airliner wasn't in danger, and it didn't break the sound barrier (this only occurs when you pass a certain airspeed: roughly 670 mph at an altitude of 30,000 to 40,000 feet.)
Surely you know that airliners almost always fly at the same altitude, approximately 30,000 feet. After the take-off, it takes about 20 minutes to reach its cruising altitude.
At 30,000 feet and higher, it is also possible for aircraft to avoid weather systems, making it more comfortable onboard. Referred to as turbofans, the engines on modern jet-powered airliners are most efficient when used at high altitudes.
The highest verified altitude you can skydive from in the United States is 30,000 feet. For context, this is in the range of standard cruising altitude for a commercial airline and about 7 miles up. In other words, much higher than your average skydive at 10,000 feet or nearly 2 miles up!
Aircraft with fixed wings cannot stand still in the air, unless we are talking about VTOL (Vertical Take Off and Landing) aircraft. Lift is created by air flowing around the wing. Too little forward speed, and the wing will stall (loose lift).
A: No commercial or business airplane flying today can exceed 100,000 feet. Special rocket-powered airplanes can fly over 100,000 feet to gather data, but they are specially designed for it.
The highest certified altitude of an airliner was Concorde's 60,000 feet. Today some of the corporate jets can fly at 51,000 feet. Q: What is the highest cruising altitude allowed? A: Most airliners are limited to 45,000 feet or less.
Many large widebodies have a ceiling of up to around 43,000 feet (12,500 meters). The Airbus A380, for example, is 43,100 feet and the A350 and Boeing 787 are the same (although the larger 787-10 and A350-1000 are lower at 41,100 feet and 41,450 feet).
Most commercial airplanes have a certified maximum altitude of about 40,000 to 45,000 feet. Regardless of its certified maximum altitude, if an airplane flies too high, it may fail in one or more ways. For starters, the engine may suffocate from a lack of oxygen.
Over the course of less than six minutes, the plane descended 18,000 feet, ultimately moving from flying at 30,000 feet to a level closer to 10,000 feet.
Because of its vast size, crossing the Pacific Ocean requires a staggering quantity of fuel. However, most commercial aircraft do not fly directly over the Pacific Ocean; instead, they choose what are known as 'curved paths'. These paths offers a faster, more efficient route given the curved nature of the earth.
At night pilots will turn their gaze from outside to inside and use the artificial horizon. The artificial horizon is normally a simply globe split into two hemispheres. Using this instrument, the pilot can determine whether the aircraft is in a climb, a dive, or rolling.
Specifically, the cruising speed of commercial airliners is typically around 550-600 mph, or Mach 0.85. Takeoff and landing speeds are much slower, typically between 130-180 mph, depending on the aircraft and weather conditions.
