I was mid plane and they were already out of the main beef entree....ugh!

I didn't have much experience with Cathay Pacific airlines because of delay and missed connections, the bulk of the trip was on Japan Airlines.

Flight delayed first from bad weather, then after boarding there was a problem with the plane. We had to get off and onto another plane...connections were missed and the trip took an additional 10 hours!! Pre-paid seatting was not honored due ro last minute carrier changes. Most of the trip was on Japan Airline.

Vegetarian options should be included with every meal. Even just simple steamed vegetables and whole grains would capture a wide audience.

Cramped, hot and the plane was grubby. Also the plane was an hour late and it took an hour to get my luggage once I got to LAX.

Extensive delays, poor organization to board people, as it felt like chaos to get inside of the plane. No lines, everyone gathering together like a mayhem, very confusing. Passengers out of hand and rude, which is not the airlines fault. However, there should be rules, e.g., not letting one passenger take 2+ spots in the overhead bin.

The crew, pilots and flight attendants were all amazing. What could be better is reinforcing that seats cannot be reclined at departure and landing. I had a person seated in front of me who had her seat all the way inclined, including during take-off - after the crew asked her to seat upright. Cathay Pacific should reinforce this safety request and perhaps penalize those who don't follow it. I felt very unsafe with this person limiting my space and perhaps putting my life in danger in the "unlikely" case of an emergency.

The bed was alright in business class. Food variety and quality were not up to the mark compared to the business class airfare.

Food , drink experience were great with Cathay. Crew service was excellent. Clean toilet and full snack bars always, pilot took of 26minutes later when boarding at Hong Kong with extra US customs check at gate 9 for US flight, but he managed to arrive only 2 minutes later from flight tracker. Smooth flight .

Great service from crews and delicious dishes, snacks and drinks. Egg tarts and local dimsum are delicious.
