If your flight is cancelled, there are several steps you can take. Firstly, contact the airline to find out more information and discuss alternate arrangements. Depending on the conditions, you may be entitled to a refund or even a rebooking at no additional cost. If your airline is unable to provide these services, look into other travel options such as alternate flights or ground transportation. Additionally, consider the amount of time it would take to reach your destination and arrange for accommodations if needed.
