Excuse me, where is the boarding gate?
dov-È — the accent on è signals open 'e'. Gate is borrowed from English, pronounced GEH-teh in Italian.
Use this in the airport terminal when you cannot find your boarding gate. Ask any airport staff member or at an information desk.
Dov'è is an elision of dove + è (where + is). Gate is used directly in Italian airports — no Italian equivalent is needed. Imbarco (boarding) comes from imbarcarsi (to board a vessel or aircraft).

Large airports like Fiumicino use internal buses or trains between gates
Rome Fiumicino has four terminals — T1 for domestic, T3 for international Schengen and non-Schengen. Knowing your terminal in advance saves significant walking time.
