I'm going to HKG in one month (UA, from ORD), and I've been hearing that the carry-on policy at the airport is very strict. That is, absolutely only one carry-on item per person, within allowable limits. Does this mean I cannot bring a small rollaway carry-on (the size just slightly smaller than typical max), plus a small shoulder bag? Can anyone clarify this, and share their experiences (if in fact they really are THAT strict)? I'm only going there for four days, and would really really prefer not to have to check in any bags on the way back. I pack light anyway, but I might buy things in HKG that I'll want to bring back in to the US. Thanks in advance.
