Air Waybill numbers issued by Rio Sul Serviços Aéreos Regionais begin with 310. For example, a typical AWB number would be 310-12345678.
This carrier has ceased operations. Codes are retained as historical reference and may since have been reassigned.
No Rio Sul web property survives, so no carrier-published cessation notice was reachable. Finding rests on both code registries having reassigned its identifiers: ICAO RSL now Panama Aircraft Rental (FAA), IATA SL now SAS Connect / Thai Lion Air. Codes SL/RSL/310 kept as historical fact.
