Actually, in many cases, this is impossible to do. The strongest thunderstorms can climb 50, to 60, feet. That's well above the typical cruising altitude of 35, feet. Even if you can fly over a thunderstorm, turbulence can be a minor problem from weakening updrafts over the storm.
Most pilots will avoid thunderstorms by either flying around them if they are singular thunderstorm towers or through weaknesses in storm severity if the plane is punching a squall line or frontal boundary. In either case, cloud tops can rise way above the altitude of the plane. It is impossible to get that door open at flight level "even after six cups of coffee and the aggravation that comes with sitting behind a shrieking baby," according to the Ask the Pilot blog.
The pressure differential between the outside roughly millibars and inside of a pressurized plane to millibars is too great for any human to break. The door to the plane acts like a cork that must be opened inward, but the higher interior pressure holds it in place until the plane descends.
It ranked 20th out of 30 in on-time departures in , which is actually a dramatic improvement over the previous year when it ranked 28th.
Of course, the answer is complicated, but for the most part, the main reason is capacity. SFO's runways are too close together to allow simultaneous operations during wet weather. Due to environmental concerns read about that here , there are no current plans to further separate the runways, which would require expansion into the Bay. SFO runways are designed to handle up to 60 aircraft arrivals per hour in dry weather.
That's because the airport operates two sets of parallel runways — one set for takeoffs, the other for landings. These pairs of parallel runways intersect at their midpoint forming a giant "X. During dry weather, two streams of planes can land and take off from these parallel runways.
The problem is that planes are only allowed to take off and land simultaneously on these parallel runways during clear, dry weather.
When air traffic controllers switch to the Southeast plan see map , simultaneous operations on parallel runways used to be forbidden, which cuts the airport's capacity about 60 landings per hour in half during storms. Prior to this, bad weather days reduced the arrival rate to as low at landings per hour, but these enhancements now allow as many as 36 per hour in bad weather. Air Travel. Business Travel.

The main and overriding reason are extreme, unpredictable, and often suddenly varying winds. Pilots do not only avoid thunderstorms while landing, they avoid them for takeoff as well as in the en-route flight environment.
At altitude, assuming the aircraft has slowed dow. Lajos Schonheinz Pundit. Can wind take down a plane? Planes like to take off into the wind , because it's the only thing in aviation that's free and provides lift. When air flows over the wings, flight happens, and the wind helps with that during take off.
Zixuan Hennersdorf Pundit. How many times can your flight be delayed? Federal rules mandate an airline cannot keep you in a plane on the tarmac more than three hours on a domestic flight , or four hours on an international flight , without returning the aircraft to the gate and letting passengers get off. Maeva Calomarde Pundit.
Which airline has most delays? Mehdi Salanova Pundit. How much compensation do you get for flight delays? The amounts of compensation are based on the length of the delay and the flight distance. Lira Sainz De Maza Pundit. Can I get compensation for a 2 hour flight delay?
