I liked the movie selection. The food was average and I appreciate that they even served a breakfast about an hour before landing. Service on board was average. Somehow, I had expected more smiles and aloha from the flight attendants. Flight was packed and the ground staff handled the Boarding very expeditiously. Upon reaching home, I realized that my baggage was damaged. Is it still ok to file a claim?
