Flights get canceled at the last minute due to a variety of reasons, primarily centered around ensuring passenger safety and operational efficiency. Weather-related issues such as storms, fog, or volcanic ash can render flying unsafe, prompting airlines to cancel flights. Technical problems with aircraft, discovered during pre-flight checks or even just before departure, may also lead to cancellations to avoid potential risks. Operational delays at airports, congestion on runways, or air traffic control issues can disrupt flight schedules, necessitating cancellations to maintain order and safety. Regulatory compliance, crew availability, and commercial considerations further influence these decisions. While frustrating for passengers, these cancellations are crucial for maintaining the integrity of air travel operations and ensuring the well-being of everyone involved.
