幫你查了一下：CX同ZH是有interline agreement的，而且國泰也說他們會幫你做through check.但如果是第一段partner航司的就由他們決定。深航沒有在網站上承諾任何東西。
因為簽有interline，所以技術上是完全可以操作得到的，但這個很看checkin agent的能力，因為操作上有點複雜的。 一般大的國際航空在base或者大的外站裡senior一點的員工懂得操作的機會最大。
我之前的經驗，很多櫃檯的員工搞不掂甚至不知道有這個東西，但和他們說能不能請superviser幫幫忙，基本上都you80%左右成功率。 但我覺得南京本身就沒有太多國際航班，加上又是深航的外站，我不抱太太希望。 但不用怕，你有5個鐘轉機時間，到了HKG去CX的轉機櫃檯讓他們幫你，你也不用自己出去拿回行李。
===========================================
What is Cathay Pacific's separate ticket through-check in policy?
As a courtesy, Cathay Pacific will through-check you and your bags to your final destination if you are travelling on separate tickets involving connections with our interline partners. However, through-check may not be possible on your return journey if it begins with an airline that does not provide a separate ticket through-check service.
Passengers holding connecting itineraries booked on a single ticket or connecting between Cathay Pacific operated flights will be through-checked to their final destination regardless.
