I'm flying with my wife and infant one way from Bangkok to Chicago with a 2 week stop in SFO on the way. If I purchase this as one multi-city itinerary at cheaptickets.com or vayama.com will I get the international luggage rate on the domestic flight to Chicago since it's the final stop on the itinerary? We'll be maxing out the luggage allowances. I work in Asia and so whenever we do get back to Chicago I'm always loaded, but I've never had to make a stop in between like this before. Thanks for the advice!
