AC6614 still shows as a codeshare flight from PEK-CTU at 1900hrs daily, but you won't get a good fare using a codeshare
Perhaps you mean
you won't get a good fare using a codes share with Air China
Consider this as a warning to avoid a lacklustre airline. FT is full of alternative Chinese airlines that are of better quality to CA such as Hainan, or China Southern. If seeking reliability and quality, then look towards Cathay in HKIA. If you wish to be avante garde as well as seek comfort and quality, then transact with the capitalist running dog rebels, EVA. the airline of choice for all those who dare to be different and wear a bit of colour.
