You need to contact the airline with whom you booked your ticket for exact information. Or you can go to that airline's website. Most airlines allow 1 carry on suitcase and 1 carry on personal item (ie: a purse or small backpack) per person at no charge and the fee for the first piece of checked luggage per person is $25-$35 and goes up from there unless you are a credit card holder with that airline (most allow credit card holders 1 free checked bag) or are a "frequent flyer" on a specific airline and are part of their miles program. Again, for specifics you need to contact the airline you are flying with. My statement is merely general information.
It is different per airline, website check for the carrier is best
