我想先去MM学校，带着行李去。几天后再回加州我的学校，美国的航班有规定多少行李吗？我还可以带那么多行李吗？

Checked baggage weight/size/number limits vary depending on the
airline, the class of fare, and the country of origin. For US domestic
flights, one is typically limited to 2 pieces of checked baggage
(excluding luggage carriers), each of which has a total length + width
+ height less than 62" (or 72") and weighs less than 70 pounds (32
kg). For domestic travel within a foreign country, however, the limit
is by weight, not piece count, usually 20kg.
好像这里说国内国际规定一样的!
