Issues: 1) the charging issue as described in my previous survey 2) when I requested diet coke during the breakfast time, it is not available. Why? I can't drink diet coke in the morning? 3) when I tried to transfer to this flight, its gate information was not available to me?

The lead business class attendant was excellent. Made a point of greeting you and knowing your name by the time you leave.

A lot of things Never flying with this airline again Had an emergency landing

Chicken pieces were too big with pasta. Need to be smaller.

My connecting flight was canceled or never existed. My stopover went from 1 hour and a half to 10 hours. It was a long day that I wasn't prepared for and it would have been nice to know that ahead of time. Cathay is great though. Great staff, entertainment and food.

Boarding at the airport was not well managed. Otherwise, had a good flight sitting in the first row (which I paid for). Crew was pretty friendly, and flight was smooth.

Just want to do a little more clean up so does not smell like urine.

Check in process at the kiosk, crew in flight and overall comfort was good. Food selection could have been better. Flight from Hong Kong to Los Angeles did not have any vegetarian main course option, it was either sea food or chicken. Being a vegetarian I could only eat yogurt and fruit. Most international flights have one vegetarian main course dish which I found missing in Cathay Pacific menu.

Great. Efficient boarding process with the face recognition. Plenty of cabin space for luggage.

As before, my only problem was not being able to download my boarding passes prior to arrival at the airport. Everything else was perfect.

Flying on the Boeing 787 from Seattle to London was everything that I expected. Every thing was great.

Seat pitch is not enough to eat comfortably. When seat in front is reclined, your screen comes closer to your face. Ryanair seats are actually more comfortable.

Overall, it was basically good. No serious complaints on my end.

The leg from Portland to Heathrow was great for a business class ticket. The BA leg from Heathrow to Lisbon was terrible. Basically coach seating with an empty seat between you and next passenger. Absolutely no leg room. Should not have been charged for business class and it was a 3 hour flight.

The aircraft was okay and the crew were friendly, but the seat space felt too tight and the food could be better. Overall, nice service but room for improvement.

The flat beds. Other than that, the place was not clean.

It is a wonderful airline. The cabin crews were friendly and the food as well as the service the were excellent.

Good but could be better for comfort and entertainment aspect

Overall it was not a pleasant experience, I was given the middle seat even though I asked for a change they didn’t honor

No WiFi working on either flight. No leg room at all, the seat in front of me left dents in my knees. If I put the tray down, it was so low it was propped up by my knees. (I’m only 182.9 cm) I’m usually cool on planes, but the planes were both hot during taxi and take-off.
