A few days ago I called in to price out paying for a routing change, and the agent suggested waiting and trying to do a same day change. Within 24 hours of the original flight, I called in to try the SDC, and was told it's only LHR to either JFK or LAX. Unfortunately, I am not flying either of those routes. Anyone have any luck with SDC with a connecting city change from Europe? I'm wondering how many times I should hang up and call again.
