Since different airlines have different refund handling fee policies, the specific handling fee amount needs to be determined according to the regulations of the airline you are traveling on. Generally speaking, refund handling fees will vary depending on factors such as the time of refund, ticket price, cabin class, etc. If you canceled your flight reservation for August 19th today, August 11th, it is recommended that you contact the airline customer service directly to obtain accurate refund handling fee information. Normally, the closer the refund is to the departure date, the higher the handling fee may be.
