Worst airline company I’ve ever experienced. We had a 15-hour delay during the night without any accommodation or beverages provided. The flight attendants couldn’t provide any information about what was happening, resulting in absolute chaos at the gate with no fixed departure time. Passengers were kept waiting on a bus with no air circulation in front of the plane, rather than being allowed to wait outside. There was literally nobody working on the plane or handling any necessary tasks. In conclusion, they are inconsiderate towards their customers. Absolute chaos!
