Due to weather, air traffic control, airplane maintenance, airplane reallocation etc, China Southern Airlines may adjust the scheduled flight, including the change of airplane type or route, cancel, suspend, delay or postpone a flight.
If any of the following circumstances occurs, we can give no prior notice in accordance with the regulations:
(I) To comply with the laws, regulations and government regulations;
(II) To ensure the flight safety;
(III) Other irresistible external factors;
(IV) Other non-CZ reasons.
Due to uncontrollable or unpredictable non-CZ reasons, such as weather, air traffic control etc, the flight has thus been cancelled, brought foward, delayed, route-changed, or has led to miss a connecting flight or fail to provide regarding passengers with confirmed seats, we would adopt the following measures when considering the reasonable needs of passengers:
Provide available seats of the follow-up flight to the affected passengers on our priority list;
Conduct flight transfer procedure for relevant passengers with the consent of passengers themselves and related carriers;
If the cancellation or delay is caused by us, such as airplane maintenance, flight reallocation etc, we would adopt the following measures in addition to the two measures above: change the route of original tickets and arrange the relating passengers to take other flights or other carriers to their destination or the transit place without replenishing the price gap for flight ticket, excess baggage charge and other service fee, and even getting refund if they are overpaid.
The flight schedules are prepared four or five months before hand based on the conditions of fleets, market and other factors. Because there always are some unexpected factors such as bad weather, airplane maintenance, airplane reallocation etc when implementing the flights, and airlines have to readjust the schedules provisionally. Therefore, above-mentioned discrepancy occurs.
