Good afternoon fine folks. I have a flight from Newark to Florence on Aug. 19 with a connection in Brussels. The flights are UA flights with UA flight numbers but the connection is operated by Brussels Air. I have 1 hr. and 30 minutes between flights.. I arrive in Brussels at 7:45am (hopefully) and my departure flight is at 9:15am. Can you kindly give me an idea of whether this is a doable scenario and what the process is like:
what terminal at BRU would I arrive at?
what terminal will I depart from?
how long is the walk to the departing terminal?
will I have to go through security checkpoint?
can I get some help from airline personnel to fasttrack security line?
and any other info you can share as I'm extremely anxious about making this connection. It is the only nonstop flight to Florence from Brussels the entire day,

Thank you so much!
