So Im traveling internationally for work. Here is my schedule:
LGA-PEK - week 1
PEK-STR - week 2
STR-DUB - week 3
DUB-LHR - week 3
LHR - JFK

Now this is the first time I've been in Beijing, and I cannot believe how cheap the luggage and clothing and everything is!
I want to buy a new suitcase, and some clothes...but I am not sure how I can get it home.

For my flight from PEK-STR and LHR-JFK, I have no problems checking in 2 bags, since its international.
STR-DUB might be an issue.
But, I know DUB-LHR (aer lingus) is an issue because its a short flight.

Any ideas how I can do this?
Is there a way I can check my bag in with American (my LHR-JFK flight) from PEK and tell them to put it on my LHR-JFk flight, or something?
That bag won't have anything I need, it would probably be just a new suitcase and some new clothes.

Any ideas?

Thanks!
