Pros: Seating in standard coach compared to premium economy on US airlines. The seats reclined back enough that I actually was able to sleep most if the 13-hour flight. Meals were very good for economy. Cabin crew super polite and patient, which I've come to notice as a standard on Cathay. As an example, I have a good intolerance to shrimp/prawn. My outbound flight LAX-HKG, the dinner salad included shrimp. I explained i could not eat the shrimp. The attendant was kind enough to swap it with a leftover vegetarian salad.
Cons: Trying to setup special meals to avoid food allergies is non-existent. Cathay offers many special meals, excluding food allergies or low-carb. I attempted to call in to Cathay to explain I could not have shrimp/prawn. The rep either did not understand or could not help. I really wished Cathay offered a pre-arrival meal like the other airlines. LAX-HKG and HKG-LAX are 13+ hours. Cathay offers a departure meal and a mid-flight meal. But by arrival time, I was starting to get hungry again. Thank God, I had enough of a layover, even with CBP processing, to grab a quick bite before continuing an additional 6-hours to home with no time to eat.
