Looking at KBLM, I noticed another unknown ICAO airline code. This time it in TKK. Does anyone know who operates TKK? I’ve looked, and can’t find anything. The flight in question is TKK728.

I’d bet that the aircraft is N728CL, used to fly under ELJ728

They are in the world famous FAA Order 7340.2.

[faa.gov/air\_traffic/publicat … CNTHME.htm](http://www.faa.gov/air_traffic/publications/atpubs/CNT/CNTHME.htm)

The Order lists general aviation contractions (FAF, OM, stuff like that), aircraft type designators, and aircraft company three letter ID’s and “telephony”, ( callsigns).
