I"ll be flying to HKG in a few weeks with lots of luggages. So basically, there's no fast way to check in but to line up with hundreds of ppl?

Also, when I was flying to US, they made us carry our luggages with our carryons through US customs even after our luggage was tagged. This is absolutely ridiculous as they don't allow us to take carts through customs.

Do we have to do that for international? Or do they just tag our bags and take them away.

I am going to have 2 luggages + 1 rolling carryon. If they don't take the luggages I dont' know how I am going to walk around with 3 luggages and 2 hands.
