I left something on the plane. Who should I speak to?
di-men-ti-CA-to — stress on fourth syllable. ri-VOL-ger-mi — reflexive verb.
Immediately after disembarking when you realise you left an item on the aircraft.
'Ho dimenticato' (I forgot/left behind) is the passato prossimo of 'dimenticare'. 'A chi devo rivolgermi?' (who should I speak to?) uses 'rivolgersi' (to address oneself to / to turn to), a reflexive verb essential for navigating bureaucratic situations in Italy.
Ho perso il mio telefono a bordo.
I lost my phone on board.
'A bordo' means on board — used for planes, ships, and trains
C'è un ufficio oggetti smarriti?
Is there a lost and found office?
'Oggetti smarriti' is the standard Italian term for lost property
Posso rientrare sull'aereo a cercare la mia borsa?
Can I go back on the plane to look for my bag?
Usually not possible — staff will check for you
If you leave something on a plane, contact the airline's ground staff immediately before the aircraft is cleared. Items found during cleaning are handed to the airline's lost property office. Recovery is not guaranteed and can take days. Always photograph important documents before travelling.
