My wife and I are coming to Kunming from the U.S. next week. We fly to Pudong one night, then the next day take a flight on a separate itinerary to Kunming from Hongqiao, on Air China. We have 12 hours in Shanghai.
Since we're to be in Yunnan for a year, we're bringing a bunch of stuff -- fine for the international flight, but far above the Hongqiao-Kunming 20kg weight limit. Could anyone provide us with information on (1) what the excess weight fee is likely to be and (2) any ways of mitigating it?
