A commercial airplane typically takes between 20 and 30 minutes to descend from cruising altitude to the runway. The exact time depends on how high the plane is flying, how far out the descent begins, and whether air traffic control asks the pilots to slow down or level off along the way. A flight cruising at 35,000 feet on a smooth, uninterrupted path will usually be on the ground within about 25 minutes of starting its descent.
How Pilots Calculate When to Start
Pilots use a simple rule of thumb called the “rule of threes.” Take the altitude you need to lose in thousands of feet, multiply by three, and that gives you the distance in nautical miles from the airport where the descent should begin. A plane at 36,000 feet needs to lose 36 thousand feet, so 36 times 3 equals 108 nautical miles. That means the crew starts descending roughly 100 to 120 miles from the destination.
At a typical ground speed of 400 to 500 knots during the early part of descent, covering that distance takes somewhere around 20 to 30 minutes. The plane doesn’t just dive, though. It follows a gradual path, losing altitude at a steady rate while simultaneously slowing down as it gets closer to the airport.
How Fast the Plane Comes Down
Commercial jets descend at roughly 1,500 to 3,000 feet per minute during the main portion of the descent. At 2,000 feet per minute, a plane starting at 35,000 feet would need about 17 to 18 minutes just for the vertical portion. But the rate isn’t constant. Early in the descent, pilots may come down at 2,500 or 3,000 feet per minute. As the plane gets closer to the airport and slows down, the rate drops to around 1,500 feet per minute or less.
There’s also a comfort factor at play. While the plane itself might be descending at 2,000 feet per minute, the cabin pressure changes much more slowly. Aircraft are designed to limit the rate of cabin pressure change to about 450 feet per minute during descent. This is why your ears might feel some pressure but you’re not in real pain. The pressurization system gradually brings the cabin from its cruising pressure (equivalent to about 6,000 to 8,000 feet of altitude) down to match the elevation of your destination airport.
The Stages of Getting Down
A descent isn’t one continuous slide. It happens in distinct phases that each add time.
First comes the initial descent from cruising altitude. The plane leaves its cruise level and begins a controlled descent toward the airport’s terminal area. During this phase, the aircraft is still moving fast and covering a lot of ground. This is the longest phase, often lasting 15 minutes or more.
Next is the approach phase. Once the plane reaches the area around the airport, typically at around 4,000 to 6,000 feet, it transitions into a series of speed reductions and configuration changes. The landing gear comes down, flaps extend, and the aircraft lines up with the runway. The final approach itself follows a standard 3-degree glide path, which is gentle enough that you barely notice the angle. Pilots calculate the required descent rate on this final segment by multiplying their ground speed by 5. At 140 knots, that works out to about 700 feet per minute.
The approach phase can take anywhere from 5 to 15 minutes depending on how busy the airspace is and how the airport’s arrival routes are structured.
Why Some Descents Take Longer
The single biggest variable is air traffic control. At busy airports, controllers frequently ask planes to slow down, hold at certain altitudes, or fly extended paths to maintain safe spacing between aircraft. A controller might clear a plane to descend to 12,000 feet, then hold it there for several minutes before issuing the next descent clearance. These step-down instructions can easily add 10 to 15 minutes to what would otherwise be a straightforward descent.
Speed restrictions also play a role. Below 10,000 feet, all aircraft in the United States are required to fly at 250 knots or less. Controllers may impose additional speed limits at various points along the arrival route, and when they combine a speed adjustment with a descent clearance, pilots execute them in sequence. Being told to slow down first and then descend takes longer than doing both at once.
Wind is another factor, though its effect on descent time is smaller than most people assume. A strong headwind during descent means the plane covers ground more slowly, which can extend the clock by a few minutes. Tailwinds have the opposite effect, pushing the plane toward the airport faster. Where wind really matters is on the final approach and landing. Each knot of tailwind increases landing distance by about 3 to 5 percent, which is why airports almost always land planes into the wind.
Emergency Descents Are Much Faster
If a plane loses cabin pressure at high altitude, the crew will perform an emergency descent to get below 10,000 feet as quickly as possible. At that altitude, the air is dense enough to breathe without supplemental oxygen. Pilots are trained to don oxygen masks within 5 seconds of recognizing the problem and immediately configure the aircraft for a rapid descent.
Emergency descent rates can exceed 5,000 to 6,000 feet per minute, meaning a plane at 35,000 feet could reach breathable altitude in as little as 4 to 5 minutes. These events are rare, and the descent feels dramatic to passengers, but they’re a well-practiced procedure designed to prioritize getting to safe air as fast as possible. The crew then either continues to the destination or diverts to the nearest suitable airport.
What You’ll Feel as a Passenger
You’ll usually notice the descent starting about 20 to 30 minutes before the scheduled landing time. The first sign is often a subtle feeling of the nose dipping slightly, followed by a reduction in engine noise as the pilots pull back the throttles. Your ears may start to feel pressure as the cabin gradually repressurizes to match the destination’s elevation. Swallowing, yawning, or chewing gum helps equalize that pressure.
As the plane gets lower, you’ll hear more mechanical sounds: the flaps extending, the landing gear deploying (usually a thump followed by a rushing wind noise), and occasional bursts of engine power as the pilots make small adjustments. The final few minutes before touchdown tend to feel bumpier because the plane is now in the lower atmosphere where thermal currents and surface winds create more turbulence. The entire experience, from the first sign of descent to wheels on the runway, is typically 20 to 30 minutes on an uneventful flight and up to 40 minutes or more at a congested airport.
