The cabin crew were kind, helpful, and polite. However, my flight from Abu Dhabi to Frankfurt was delayed, causing me to miss my connecting flight. As a result, my journey was significantly extended, leading to a much longer travel time than originally scheduled. I didnt get a compensation like food and accommodation.
