Family & I flew from Sydney to Zagreb via Guangzhou & Paris.
Whilst the trip was with Air France, we flew with China Southern from Sydney to Guangzhou, and then from Guangzhou to Paris.
From Sydney, we had an A380 & it was great! Seats were extremely comfortable, even for my father who is a bigger man & he said he was very comfortable. Service was great, English was quite basic but they were able to understand most of the requests & were very nice and prompt. On board entertainment was slim but still enjoyable.
The food started out quite poor, with my little brother getting a chicken & rice with the chicken completely pink inside. The rice was also undercooked so much we couldn't really chew it.
However, our later meal was a beef goulash that was absolutely amazing. So much so that we continued talking about it during our trip.
Flight from Guangzhou to Paris was also quite pleasant. My fathers screen didn't work before the flight, and so he was given a tablet to use which was great.
Food was okay on this flight, everything cooked but not very tasty. Seats were quite comfortable, enough for the majority of economy class to sleep 8+ hours.
Overall, the airline was prompt, clean & was quite enjoyable.
