As good as can be expected for economy class international flight, on time very professional crew. The plane was clean bathrooms clean, decent food, connecting flight on time, with another tasty meal. Love Cathay Pacific

Okay|Jun 2026
Cathay Pacific used to be a great airline for travel to Asia. Having travelled with this carrier many times I've noticed a decline the food quality, seat pitch, and entertainment offering. The services still remains top notch as can be said with other carriers in this class (i.e. Emirates, Singapore Airlines, etc.)
