Where is the baggage claim?
ri-TI-ro ba-GA-gli — stress on second syllable of each word. The 'gl' in bagagli sounds like the 'll' in 'million'.
Ask this after landing inside the terminal when you need to locate the baggage carousel for your flight.
Ritiro (collection/retrieval) comes from ritirare (to collect, to withdraw). Bagagli is the plural of bagaglio (luggage/bag). Together ritiro bagagli is the standard term printed on Italian airport signs.
