The flights for your vacation package are ticketed 24 hours after booking. In order to make a change (i.e. spelling correction, change of surname, date of birth correction, gender correction, etc) to the tickets the airline, IF THE CHANGE CAN BE DONE, charges a change fee of up to $350 per person plus any increase in the airfare since it was booked.  

Any changes would need to be done by calling our Contact Center and speaking to a Customer Service Representative. 

Note: Replacing a traveler with a new traveler is not a 'change' - that is considered a new ticket.
