I make a reservation and I have access to carry one bag on cabinets and one carry on bag, after I bought the reservation I called the airline to confirm and the answer was right I HAVE ACCESS TO CARRY ONE CARRY-ON BAG AND ONE IN STORE; at the time to checking in I get charged for $60 dollars on the flight going out and $30 dollars for the flight comes back. So I need the money back to my account for those changes thanks for the atención on this request
