I thought "companion" tickets are the responsibility of the other companion to book and take care of the taxes and fees. Strolling into just any airport may not produce results. I check people in and but know very little about those special types of tickets. Some of us aren't trained in reservations and are only taught how to check in and rebook during off operations. I don't work for Delta but I am sure many of the sames things occur. I would ask the person who gave you the privilege of such ticket about the rules that go with it and go from there.
