I have never heard that either KEF route is upgrade eligible and have never experienced this, but I certainly could be wrong. I know it wasn't eligible when I took it years ago, but that could have changed. I don't see any sort of exemption for it on dl.com, but that doesn't mean it doesn't exist. Especially during the summer though, there seems to be a lot of paid J traffic on these routes so even if they are upgrade eligible, I think it probably isn't likely that very many medallions get upgraded anyway.
