Sorry, I didn't mean to imply that literally you could not change your flight dates over the telephone. What I meant was if you have a higher fare class ticket with a direct carrier, you can purchase an open ended return, you can change the departure, or the return with minimal effort, and it remains the same ticket. When you purchase a ticket on a public charter, you sign a contract for a seat on specific chartered flights. Changing your travel schedule requires having that contract cancelled, and a new contract signed for a different specific flight (s). The indirect carrier may make this process fairly painless, but it's still a distinction between how an airline ticket works and how a ticket on a charter flight works.
