Dear Franya,
Thanks for contacting Top China Travel!
It is really hard to say which airline is the best. The flight delay generally has three reasons: air control, different safety standard in different airlines, and weather.
Different safety standard in different airlines
1. Different types of planes have completely different safety standards, even the weather is likely to be in the same condition, the A380 can take off but A320 can't.
2. For the same type of plane, each airline safety standards is different also. In the same weather conditions, the weather is likely to conform to the safety of China Eastern Airline standard but is not in conformity with the China Southern Airline.
3. International flights have priority right of take-off, this is an unwritten rule accepted worldwide.
4. Base airlines have priority right of take-off, such as Air China in Beijing, China Eastern in Shanghai, China Southern Airlines in Guangzhou, Sichuan Airlines in Chengdu.If you request priority of taking off, suggest to choose airlines base.
Weather
1. The weather in starting point of the airport is unfavorable to take off;
2. Destination airport weather conditions are unfavorable to land;
3. Meteorological condition on the flight route is unfavorable.
