If you have lost an item on the plane and still haven’t left the airport in that case, the first recommendation is to connect over the Hawaiian Airlines Customer Support number with the representative and ask them for the necessary help and assistance and not go directly to the airport staff. Lost an item near the Ticket Counter, Gate Area, or TSA Security Checkpoint If you have lost an item neat the ticket counter, at the gate, or somewhere during the TSA Security checkpoint, then the airlines will not be able to help you in these matters, nor will it help you much when you contact Hawaiian Lost and Found. You can best ask at the airport desk for quick help and assistance.
