The weight limit will be 50 pounds per bag. They just charge a fee if the bag is over 50 pounds, and I believe there is a fee for having two bags. DO you have two bags and a carry on? You always get a free carry on bag and a purse or tote, so it is a good idea to have a carry on and put extra things in it to make your bags weigh less than 50 pounds. And you can put extra things in your tote purse.
