Thanks Jon. That explains why I couldn't do it. I re-read the various blogs from July (travelingbetter.com wasn't working on my phone) and it appears to only be from LHR-JFK. Too bad since my alternative flight AA51 LHR-DFW has been C7 for the last 2 days, and it's way too expensive to pay for the change.
