Boarding was a hassle. When I asked if my flight class had been assigned, the staff treated me poorly. The seats were small and very hard, and the temperature was extremely hot for about half of the flight. The food was good, but there wasn't enough chicken for the entire plane, so I only received pasta with no other options. The flight attendants were not friendly at all. Overall, for a group of 24 people, it was a very unpleasant experience.
