Ice accumulation can keep planes from being able to take off, resulting in delays and cancelations.

Most airports aim to clear frozen deposits completely but where this is impractical because of low temperature and persistent snow conditions, treatment of a frozen surface to achieve adequate braking action may be undertaken.
Depending on the time of day, the runway will close for roughly 15 minutes for snow removal, according to the video. A formation of 15-23 vehicles - made up of plows, brooms, blowers, de-icers, and sanders - all clear the snow, and then a surface friction testing car follows the line.
Unlike highways, airports cannot use salt for deicing because salt is corrosive to airplanes. Although some chemical deicers are available, the deicers have negative impacts on environment.
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.
Blue ice runways in Antarctica include: Pegasus Field, Ross Dependency, serving McMurdo Station, and operated by the United States Antarctic Program (closed since 2016) Troll Airfield, Queen Maud Land, serving Troll Station, and operated by the Norwegian Polar Institute.
A crosswind above about 40mph and tailwind above 10mph can start to cause problems and stop commercial jets taking off and landing. It can sometimes be too windy to take-off or land.
Landing feesAirlines pay a fee to land at any airport and use the required facilities there. Fees vary significantly between airports and consider different factors, including aircraft type and weight, landing time, and sometimes emissions and noise.
Some other runways appear to go up and down at different points. Answer: No, runways are not flat. They are crowned to help drain water off the sides during rain, and often one end of a runway is higher or lower than the other. When preparing takeoff performance calculations, pilots include the slope of the runway.
