Overall, excellent: check-in, boarding, service, and food. The Business Class seating is a little less private and spacious than the world's premier airlines, but still very good for a long haul flight.

Overall, excellent: check-in, boarding, service, and food. The Business Class seating is a little less private and spacious than the world's premier airlines, but still very good for a long haul flight.

On time. Friendly and helpful flight attendants. The plane was clean. Having a wine available would have been nice.

cannot get seat information for LAX to IAH when check in in XI,AN

Nothing to complain of, the only reason I am not giving better marks is that I am used to flying with ANA and they are the top.

Communication between the captain/crew and the passengers needs to be improved.

Food & service very good next I will pick up again

Everything was not satisfactory - the flight was delayed, staffs were ok but they didn't speak English well. I am from east Asia (not Chinese) and they didn't care enough to remember that I wasn't Chinese but persistently spoke chinese to me. The flight announcement in english wasn't clear to understand.

I wish I had been able to choose a vegetarian meal. Crew friendly and helpful. Seat was ok. All quite efficient and pleasant. Would recommend for inner China travel for sure.

The flight is not bad, but the Business Lounge is not big enough for the quantity of people they accept and there is a limited options for food and beverages.

We bought premium Economy, thinking it would be more comfortable, but the seat is so narrow ,that my legs and feet are swollen , I can't wear shoes !
