Just booked an award trip to Tirane in May, and am mildly concerned about connections on the return flight. We arrive BER at 8:10 am on OS 223 and need to make UA 963 departing at 9:50 am. 1hr 40min seems tight, should I be concerned?

We have an even tighter connection (40min) in VIE to the inbound, but I'll post details in the proper thread.
