As US location film, this is the American built Fairchild version of the Fokker F-27 Friendship (version of Fokker F.27-100). Airline company is ALOHA, one of the earliest US operators of the type. West Coast Airlines was the first in the world to operate a scheduled F-27 flight). I believe the airport is Lihue airport, Kauai (LIH/PHLI).
This is the old Honolulu International Airport (HNL/PHNL) terminal along Lagoon Drive, across the field from the current terminal.
