I would try an agent, with the push to improve customer satisfaction lately I've noticed a difference in how they are treating pax when it comes to changes. Twice in the last month I've even had them volunteer to completely waive the change fee when making a change well outside of the SDC period. One time was over a week in advance and the other time was 3 days in advance. I didn't even ask either time, the agent just offered (which was shocking).
