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.)
