Just curious: when carrier re-price the ticket does the old information moves to the new ticket? Example if ticket is booked from TA, plated in carrier X and then I make change through carrier Y and that carrier reprice it and sends new tickets (where it do says that: "Ticket issued by Y") what info moves to the ticket?
If I do changes in the future what next agent who touches the ticket sees? Can he/she see it was originally made through travel agent? When and where it was issued? What info moves when repricing or is it plain xONEx "new ticket"?
