Transwisata Air (TWT, Jakarta Halim) has provisionally ended Fokker 100 operations following the sale of its only aircraft of the type to Iran Aseman Airlines (EP, Tehran Mehrabad).

According to Skyliner Aviation, PK-TWN (msn 11335) has been added to the Iranian register as EP-ASN but will be used for parts rather than active duty. Iran Aseman operates a fleet of fourteen Fokker 100s of which only six are active.

Specializing in passenger charter flights, Transwisata Air also operates a CN-212, a Gulfstream IV SP, a Beech (twin turboprop) BE-350 Super King Air, and a helicopter.
