We are the Liberty August 28. Have obc from an booking onboard. Tried to use them to pay for an excursion. Unfortunately they weren't on the website. I called c&a. They looked into it and said that since the reservation was with my travel partner, i.e. travel agent, we couldn't use them only she could. Huh!? I know I've done this before. I asked to speak with a supervisor. After waiting they said they would call me back. No phone call. We paid for excursion because the sale was about to end. (Price did go up an hour later.) Am I wrong about being able to use obc this way without going through ta? Plan to escalate this to executive office, unless you all tell me I'm wrong.
