Food and comfort. Rice was kinda dry and hard. Ratio of protein to starch was menial.i probably found two chunks of chicken on the stew. Seats were tight. Very cramped. It was a bit warm during the flight. My check in baggage was separated from my connection ting flight. Had to wait a few hours in the airport, costing me extra cash for the driver to wait. I dont think ill be ever flying cathay pacific ever again.
