If you've been following my postings elsewhere & wondering if we will allow ourselves to be groped & abused by TSA one last time for this trip, the answer is .... Yes!
Our itin had developed some serious schedule-change issues in both directions including a return from CGN that could not be rebooked, but after CO's customer service rep had worked on it for an hour to no avail, I didn't have the heart to cancel, so we will return from FRA. The exact dates in FRA & CGN are after 12/21 but otherwise TBD. If anyone wants to meet up in Köln or Frankfurt after Athens, please PM me.
