I enjoy looking for cheap flights,
I found this deal on skyscanner, other people might have luck looking at other dates,
When I checked 20 Sep - 10 Oct, for a family of 5, came to $1277.79, adults were ~$318 each and kids were ~$213 each
I've never flown Sichuan Airlines, check reviews first as it doesn't have the best reviews, but for under 1/2 the price of the other airliens, someone might be game to try.
Are the in-flight meals rockin?
