Hi, first time posting here. Hoping I'm not violating any reply etiquette. Please also let me know if I should be posting this on a different thread. I have 2 tickets from the 10th I'd like to exchange for the 11th. They are Parterre C1&2. I didn't realize until now I messed up on booking my flight, and this seems to be the cheaper alternative than spending another $378 to change my flight Please let me know if anyone is interested.
