We will be in China this fall. We will have several internal flights. On luggage our tour company advises:

Due to strictly enforced weight restrictions on air carriers in China, checked luggage must not exceed 44 pounds, per person. Luggage exceeding the allowable weight is subject to excess baggage charges, which can result in a considerable extra expense.

ASSUMING WE HAD A BAG OVERWEIGHT BY 5 to 10 POUNDS, WHAT SHOULD WE EXPECT PER INTERNAL FLIGHT IN CHARGES? My hope is that we can stay under but ...

Regulations in China require that all checked baggage be locked, including outside packets and separate compartments. Sturdy hard-sided luggage is recommended.

HOW IMPORTANT IS HARD SIDED LUGGAGE? We don't own any.

The Chinese government has strict regulations regarding hand-carry luggage as well. The maximum weight is 10 pounds, and the MAXIMUM DIMENSIONS are 9" x 22" x14" (including all wheels, handles, etc.)

10 POUNDS? THE CASE EMPTY WEIGHES HALF THAT!! DO THEY REALLY WEIGH CARRY ONS? I CARRY A CPAP MACHINE. IN US IT IS ALLOWED AS AN ADDITIONAL CARRY ON PIECE. WHAT ABOUT IN CHINA?
