Took ITA connecting in FCO. The new terminal is quite nice, but at 6'3", the 28" pitch on ITA was tough. Fortunately, a short flight. I know there are plenty of taller folks and not sure how they do it. Can't change seats if on UA ticket either online or in airport from my experience. I tried upgrading to Exit row or business at the in-terminal ticketing counter and gate, but they told me it wasn't possible since 016 issued. Makes the LH connections and relatively easy process of getting a decent seat (*G) or switching more appreciated. I know ITA is not fully integrated into Star Alliance yet, so hopefully that improves.
