I've only had the experience of transferring from Pudong International to HongXiao domestic in Shanghai and it was fairly easy. There are English signs pointing the direction (correctly too
)to Buses which head directly there. They're regular and quite convenient in my experience. My flight from Sydney to Shankers took 13 hours, and after the collection of luggage much longer than that (There was a delay on the baggage for some reason.)
I believe chances are, you're gonna have to lug your luggage to Hong Xiao yourself. Taxi cues are long and all those helpful people offering you a ride in the terminal (you'll soon see
) are gonna rip you off. From my experience the bus is really cheap and quite a decent form of transfer, though at that time my luggage load was light. Having said that, I should also point out that the bus only accepts RMB , so best have some on you by the time you leave the terminal. Taxi's also are only interested in RMB but those
private car drivers would be more than eager to remove fist full's of $100 notes in exchange for their services.
Still, I'd suggest not trying to make a connecting flight the day of landing, rest up in one of the hotels near either airport and hit Harbin the next day. Timing is a wondrous thing, till it goes wrong, and airports are known for throwing curve balls on times, especially the ones around this neck of the woods.
Oh. One more thing is, make sure you have some clean underwear in you hand luggage, cos after your first road trip here you need it.
Well, I did at least
