A waiver code refers to a distinct code distributed by airlines to authorized agents. This code enables agents to bypass specific ticketing regulations or limitations for particular adjustments, like name corrections or date modifications, minus any extra charges or consequences. In the context of Delta tickets, a waiver code allows for the overriding of standard rules to facilitate changes without the usual fees or penalties. Therefore, when dealing with name corrections on Delta tickets, the usage of a waiver code grants authorized agents the ability to make necessary adjustments without incurring additional costs or issues.
