Yup. I did recently (November). To and from LA-KTM-LA. With family. All Nepali passport holders. No problem at all. Cathay Pacific has an agreement with Chinese govt that passengers (Nepalese) flying via CP should not require HK visa, as long as they do not change their flight CP to any other.

This information might be kind of old, and pardon me if I am not up to date with recent changes. I got assured with this information before traveling. And, in fact i did not have any trouble.
