What is the total weight of luggage including hand luggage you can take on a flight to Chicago from Delhi?

Actually the answer is not very easy. 1. Which passenger class are you travelling?, 2. Which ticket type do you hold?, and which airline will you fly?; Generally an allowance for 20 to 30 Kg of Baggage is allowed as check-in and about 7Kg for Handbaggage, but here is volume a major question also.

(So be specific in your question and the answer will easily be answered from the Airline with whom you wish to fly.)
