The cost will depend entirely on the class of ticket you originally purchased.
You will pay anything from $200.00 to $800.00. If you bought cheap tickets you will pay the difference between that and the full Star Class fare.
There may not be any Star Class seats available.
You will not save any money by doing it at the airport so if you want Star Class I suggest you book by phone now.
