safe connection time in VIE?
I'm trying to plan an award trip for my parents, and it looks like the most convenient option would be for them to transit through VIE. However, I'm concerned about the connection time. They would be flying TLV-VIE (arriving at 18:50), and then VIE-LHR (departing at 19:45). Is 55 min. a safe connection time for them, or should I try to find a different routing?
Thanks!
