I made a reservation thru Travelistas Cruises & Tours (Sharon Miller 708-966-9828, on or about 1/8/19. A few days later, I discovered I spelled one of the travelers name wrong. I submitted Macie, when it should have been Maci. On 1/11/19, Avanti Destinations, the trip vendor, assessed a $400.00 charge to correct the spelling. Avanti Destinations deemed this $400.00 charge a "Air Cancellation Fee". As the trip is not scheduled until June 20, 2019. tickets have not been issued. A $400 charge to in essence, delete an e from the name seems excessive. Is this type of charge customary? My travel agent did everything she could to have the charge rescinded to no avail. While it was my error, $400.00 seems excessive.
