Guardiamarina Zañartu Airport WPU / SCGZ

Aerovías DAP is the sole scheduled carrier serving WPU (Punta Arenas–Puerto Williams route, confirmed on dapairline.com). DGAC administers this remote Navarino Island aerodrome directly rather than under a private concession, and no independent third-party ground-handling agent is documented for this station. Consistent with standard practice at remote Chilean Patagonian outstations, DAP most likely self-handles its own flights here (self-handled, Aerovías DAP), but no direct DAP statement confirming this was found.

DAP operates a dedicated Oficina Carga y Correspondencia (Cargo and Mail Office) at its Punta Arenas headquarters, O'Higgins 901 (tel •••, confirmed live on dapairline.com) that moves freight, mail and correspondence across its Magallanes route network, which includes the Puerto Williams service. Specific on-the-ground cargo handling arrangements at the WPU terminal itself are not separately documented on DAP's site or DGAC's airport pages.

DGAC's own AVSEC (aviation security screening/guarding) service began operating at Aeródromo Guardiamarina Zañartu on 4 November 2024, with an initial team of four officers, confirmed verbatim against DGAC's official article "PRIMERA DOTACIÓN AVSEC EN AD. GUARDIAMARINA ZAÑARTU" (dgac.gob.cl, published 29 Nov 2024) — the airport's first dedicated security detachment.

DGAC administers Aeródromo Guardiamarina Zañartu directly — corroborated by DGAC news items referring to the field's own on-site DGAC "Jefe" (chief) — and operates the ARO/AFIS (aerodrome flight information and radio office) providing flight-plan filing, meteorological/traffic briefing and aerodrome flight information service.
