While we humans would not fare to well under these cold conditions, aircraft are built to handle all types of extreme weather conditions, and flying in cold weather is one of them.

“Jet fuel begins to gel in extreme conditions and does eventually freeze, typically at minus 40 or so, although additives can be included that reduce that further,” says Haines. “Aircraft at cruising altitude will often experience temperatures of minus 50 to minus 70 F for hours on end.”
Generally airline and passenger/freight carrying operations are suspended during periods of freezing rain. Even without being prohibited by the operators manual, operations in freezing rain are difficult as the applicable Hold-Over Time from an anti-icing treatment is very limiting in freezing rain.
Since planes are designed to fly in this temperature, cold weather on the ground does not, by itself, inhibit flight. However, cold weather can impact activities on the ground. While less of an issue for take-off, an icy or wet ground can extremely inhibit a plane's ability for landing safely.

There is no single maximum wind speed that cancels flights, as it depends on the direction of wind and phase of flight. A crosswind above about 40mph and a tailwind above 10mph can start to cause problems and stop commercial jets from taking off and landing.
Most scheduled airlines avoid taking fly routes over Mount Everest. Jet aircraft fly at an altitude from 35000 to 40000 feet; the height of Mt. Everest is inside the jet plane's cruising altitude. To ensure a safe distance above the Himalayas, the pilots are required to fly into the lower portion of the stratosphere.
As we've discussed above, snow, ice, and bad weather do not hinder a flight. It remains safe to fly as long as precautious and pilot training are both up to date.
