Anyone experience with their online check in? Is it solid and reliable?
Can you check through luggage from HU to HX on separate tickets?
Will arrive in PEK T2, and looking for smooth onwards travel to HKG with a short time interval
The online checkin looks lousy but works fine. Because all Chinese carriers (including HK Airlines) use TravelSky GDS, the information integration is actually quite good even though it appears lousy.
On separate tickets, no experience checking bags through, sorry. But knowing that PEK is highly subject to delays, I'd strongly hesitate to book separate ticket connections with a short time interval--would only book if they were on one ticket so as to guarantee the connection (or, if you have travel insurance and like to gamble, feel free...)
