Help! Where do these airports go into?

[AirHanoverInternational]

I have found data for Northern Mariana Islands: Saipan, Tinian and Rota. AM shows Saipan in Northern Mariana Islands but Tinian in US Minor Outlying Islands. So were should Rota go?

Departures only:
Saipan 609,502
Rota 31,760
Tinian 39,405
