I was scheduled to leave tonight on Delta but when my flight was canceled, we were put on a Monday night flight. I asked the Delta agent on the phone to make the return trip later so we'd have more time on vacation. She made the change and transferred me to someone else for "reticketing". The new flights show on the website and I'm still waiting on hold for reticketing. What is reticketing? Do I need to stay on hold if the Delta website shows the new flights?
