How much does it cost to change a plane ticket departure date?

I am going on Continental Airlines to Venezuela on the 1st of July. How much would it cost to change it to June 22? Thanks so much.How much does it cost to change a plane ticket departure date?You need to call the airline to find out because other than the change fee, most probably you would need to pay for the difference in fare between the old and new ticket. There are only 5 days before June 22, most probably the fare is higher than the date you first bought it.
