Lapangan Terbang means airport in the Malay language.
From the dates in this collection, it would seem that this Lapangan Terbang K.K. cancellation was in use for many years. From covers which would be shown later on, the range of dates of my items is between 4-8-1974 and 19-10-1993. Unless I am missing a postmark in between, it was likely that it was used until 2008 when the LTA (Lapangan Terbang Antarabangsa) was introduced with the opening of the international airport.
