Going back home with too much bagage

I'm getting ready to go home, but I got way too much stuff. About 20 Kg overweight. Is it cheaper to send it by mail, or to pay for an extra suitcase? I'm going from Changsha to USA

I think is better to pay extra for you to get all things with you to avoid other up and down when you get back home. Save Journey.

It is worth checking the airlines. One offers economy with  2 x 23kg. One (or two) offer 2nd case at lower rate. So check your best price offer for the flight and then check baggage allowance. You may find a higher flight ticket offers overall best price, Normally, excess baggage charge is 1% of First Class airfare.
Safe journey

Hi Belkys2015,

I moved your thread to the USA forum so as you can get more feedbacks from members in USA having had the same issue.

Have a safe journey, :)
