- Too heavy? Overweight 23-32 kg is only $70, but if total bags exceed free allowance, the 3rd+ bag costs $100-$200. Split weight across travel companions’ names
- Shoppers: Choose China Southern/JAL — 2 free bags suits heavy shopping round trips

6. FAQ
Q1: Does carry-on baggage count toward checked allowance? A: No. Carry-on bags (typically 7-10 kg, within 51x40x23 cm) don’t count toward checked bag limits. As long as carry-ons meet size requirements and stay within weight limits, they’re free.
Q2: Can two passengers combine their free checked allowances? A: Yes. Passengers on the same flight can pool checked bags (e.g., 2 people with 1 free each = 2 bags total), but individual bags shouldn’t exceed the weight limit (23 kg) — overweight fees apply per bag, not per person.
Q3: Is the return trip (from China) baggage policy the same as outbound? A: Not necessarily. For China-US round trips: outbound policies follow the airline you’re flying; return policies follow that segment’s airline rules. For example, outbound on United (1 free bag) vs. return on China Southern (2 free bags) means different allowances — check each separately.
Q4: Can bags over 32 kg really not be checked? A: Most airlines refuse single bags over 32 kg as regular checked baggage — they must be split or shipped as cargo. A few airlines allow overweight bags for $200-$300 special handling fees. Apply in advance or buy extra suitcases to split the weight.
Q5: Do business/first class tickets get more baggage? A: Yes. Business class typically gets 2 free bags (China Southern/JAL: 3), first class gets 3. Weight limits are also higher: business class up to 32 kg/bag, first class up to 45 kg/bag. See each airline’s website for details.
