If China Southern Airlines can not provide the cabin of the original class due to the change of flight or plane, China Southern Airlines will do our best to arrange as you wish. If passengers do not accept the arrangement, involuntary refund shall be permitted.

Whether another flight can be arranged after the cancellation is determined by the following factors: the approval of the air traffic control, transfer of passengers to the next day, duty time restriction of aircrew and plane condition. In addition, flight safety and airworthiness is also taken into consideration.

Normally speaking, the carrier will consider to arrange another plane and aircrews if available so as to avoid long-time vicious delays of flights.

After a flight is cancelled, the carrier will provide passengers with the closest subsequent flight or the closest flight of the most suitable for the travel of passengers. Once the flight is changed, the contract of buy a new ticket shall be deemed to have been established. If passengers do not accept the arrangement, they can refund the tickets in full amount according to provisions of involuntary refund. If it is inconvenient for passengers to refund the tickets at the time, they can go to ticket offices directly affiliated to China Southern Airlines and show the corresponding certificates to refund their tickets within the valid period of the tickets.

There are many reasons for the carrier to cancel or merge flights due to the delays, such as Airline Corporation itself, air traffic control, airport and national important activities, etc. If the delay is for the reason of the carrier itself, on the one hand, the carrier will make compensation for the loss of passengers' rights and interests. On the other hand, the cancellation and merger of flights is to maintain the rights and interests of passengers, reducing the impact on subsequent flights and restoring flight operation as early as possible.

"Involuntary Refund" refers to the fact that passengers require the refund for their tickets if the carrier cancels, delays, changes the flight, flies ahead of schedule or fails to provide the booked seats.

Unless the law provides otherwise, China Southern Airlines will offer the following services for your selection if the cancellation of a flight leads to the late takeoff of your flight, the failure of landing on the destination or stopover, or the missing of booked connecting flight:

Arrange the earliest flight of China Southern Airlines with available seats free of charge or prolong the valid period of tickets if necessary;

During the reasonable period of time, arrange flights of our airline or other carriers free of charge via the change of route, or send passengers to the destination stated on the thickets via other traffic ways acceptable to both parties, without additional charges;

Refund tickets according to provisions of involuntary refund.

Help for abnormal flights:

When the flight is delayed or cancelled due to the faults of China Southern Airlines, such as plane maintenance, flight allocation, business, and aircrew, dynamic information and food and accommodation for the passengers will be provided free of charge by China Southern Airlines as appropriate.

If the delay or cancellation occurs at departure due to the reason not related to China Southern Airlines, such as weather condition, unexpected event, air traffic control, security inspection or passengers' fault etc, China Southern Airlines will offer the dynamic flight information and assist in the arrangement of food and hotel accommodation for passengers at their own cost.

If the delay or cancellation occurs at the stopover, China Southern Airlines shall be responsible for offering food and accommodation for passengers free of charge no matter for what reason.

If any of the following circumstances occurs, China Southern Airlines is free from any prior notice of change of the type of plane or flight course, and will cancel, suspend, delay or postpone the flight in accordance with relevant regulations:

To follow the law, regulations, rules, command or requirement;

To ensure the flying safety;

Other uncontrolled and unforeseeable reasons.

If the carrier, due to any of the above reasons, cancels or delays a flight, and correspondingly fails to provide passengers with the booked seats (including cabin class), or fails to stop at the stopover or destination for passengers, or makes passengers miss the connecting flight, China Southern Airlines would adopt the following measures when considering the reasonable needs of affected passengers:

To arrange the following CZ flight with seats available;

To endorse with the consent of traveler and relating carrier;

To change the segment listed on the original ticket, and arrange CZ or other flights to send the passengers to destination or stopover;

To deal with it according to involuntary refund rules.

China Southern Airlines shall adopt all necessary measures to avoid the delay of passengers and their baggage transportation. China Southern Airlines shall not assume any responsibility for that if it has adopted all necessary measures or can not adopt those measures.

At present, flight delay is the major reason for passengers' distrust upon the carriers and this is actually the shortcoming caused by the continuous provision of delay information. Each airline corporation has a dispatching center carefully arranging the flight of all planes. Once there is a problem at the operation, such as plane failure and airport closing, the whole flight will be affected. The dispatching center will make adjustment in time in the light of the actual situation so as to restore the normal flight operation as early as possible, notify the subsequent flights to make the corresponding preparation, and estimate a rough delay time. But the situation keeps on changing, and there might be new situations in the process of dispatching. A new delay can lead to the change of plans, thus making a flight put off again and again.

There are many planes taking off and landing in airports, especially in busy ones. To ensure the safety of operation, air traffic control department, in the light of flight flow in the air and on the ground, commands and controls planes in airports, requiring them to glide and take off at the safe interval. In some busy airports or at peak hours of general airport, air traffic is overloaded, so be ground traffic. In the case, it is normal that planes have to glide on the runway and even wait for much longer time.

The reasons are as follows:

1. The standard of takeoff and landing is related to the aircraft, and different airlines may have different safety standards for the same craft;

2. The captain is entitled to reject to fly when the civil aircraft, airport, and weather condition do not accord with the regulations, and flying safety cannot be guaranteed based on the civil aviation regulations. Captains may have different decisions.

After cabin doors are closed, and everything is ready, the captain needs to make departure application to the air traffic control department. The air traffic control department determines whether the plane can take off according to the traffic flow. Other planes are not subject to the control of the traffic flow due to different destinations and directions.

As for the same flight, the carrier, airport, and air control department might obtain different information from different resources. But as a carrier, our corporation will inform passengers of delay information as soon as possible.

The takeoff of all flights on the same airport is based on a series of orders of air traffic control department. Air traffic control department determines the priority sequence of takeoff of planes in the light of captains' departure application times. And the captain can not make the departure application unless cabin doors are closed and everything is ready for takeoff. Therefore, the earlier the application is made, the shorter passengers need to wait.

Delay for dispatching reason refers to the time delay caused by the China Southern Airlines' adjustment to the flight in the light of needs in the process of flight operation; delay for plan reason refers to the delay of subsequent flights due to deficient plan time of flights segments or deficient turnaround time of flight in plan formulation.

When the flight is delayed or cancelled due to the reasons of China Southern Airlines, such as plane maintenance, flight allocation and aircrew conditon, food and accommodation for passengers shall be provided free of charge by China Southern Airlines as appropriate.

If the delay or cancellation occurs at the departure due to reasons not related to China Southern Airlines, including but not limited to weather condition, unexpected event, air traffic control, airport fault and passengers' problem, etc, food and accommodation shall be arranged by China Southern Airlines at the passengers' cost.

If the delay or cancellation occurs at the stopover, the carrier shall be responsible for offering food and accommodation for passengers no matter for what reason.

Firstly, when a flight has been delayed for a long time, the carrier may shorten the delay time via the adjustment of flight operation plan, including the transfer of backup planes. But the backup planes are not available at every airport; secondly, temporary plane transfer plan is subject to the approval of air traffic control department. Therefore, even though there are backup planes, they may not be used for flight.
