My parents are on 907 a few weeks from now...obviously there's a good amount of time for this situation to resolve itself but absent that, what if anything would happen to my parents? Would they be re-routed via, e.g., EWR? My mom's getting a little anxious. They have an onward connection from Frankfurt (thankfully at least the scheduled layover following 907's arrival is nearly 4 hours). To make it even more complicated, flights were booked as part of a tour package...
