There is no charge. The greatest thing about this company is that you have one year to use them from the time you buy them. I found this out because I had a flight that got canceled and another that got delayed all in the same day because I was flying cross country and so I was unable to make it until the next day for the bus. When I called them that's the answer they gave me. These guys of the only ones I go through for that reason. Its awesome!
Not sure the cost . Your best bet is to call them
