How to treat flight delays caused by weather, air traffic control and other reasons?

In fact, the impact is not as great as expected ~ some people say that airlines can push all the delays to the weather, and passengers are not fools. How can they be so gullible? I flew about seven or eight times this year ~ Fortunately, a flight with mechanical failure returned, and the airline arranged accommodation, and each person paid 200 yuan ~ without encountering the delay or cancellation at his own expense mentioned in the regulations. From this point of view, in fact, the probability of traveling by plane is still relatively low!
