I bought tickets from SAS months before departure. A few weeks before departure I was told that the flight times had been changed from Friday evening to Friday morning. I have indicated that this is not possible, because one of the passengers is a child. A child must go to school according to Dutch law. SAS suggested to leave 2 days earlier on Wednesday morning. I indicated (for the 2nd time) that this is not possible, because my child has to go to school. When they refused to offer a solution, I complained. SAS replied that the processing time is 6 to 8 weeks, while I have to fly within 4 weeks. I have not heard back from them yet. They claim to be a member of Star Alliance, but they cannot compete with KLM or Turkish Airlines. SAS is really a disgrace to the Star Alliance label.
