The answer to this question is not as cut and dry as you might think. There are a variety of factors that go into deciding whether or not to cancel a flight due to weather. The primary concern of airlines is always the safety of their passengers and crew. If there is any doubt that flying in certain conditions is safe, the flight will be cancelled.
However, that doesn’t mean that every flight that is affected by bad weather will be cancelled. If the weather is not expected to be severe enough to pose a safety hazard, the flight may still take off. For example, if it is only lightly raining at the airport, the flight may still depart.
It is also worth noting that airlines will often cancel flights in advance if they know that the weather is going to be bad. This is to avoid the inconvenience of passengers being stranded at the airport. So, if you are planning to travel during a time when the weather is expected to be bad, it is always best to check the flight status in advance.
