Overview
Port Walter Seaplane Base (PWR) sits in Port Walter, Alaska, where it functions as a seaplane base. Free of scheduled airline operations, it serves business aviation, charter flights, and local general aviation.
While no charter operators list PWR as their home base, the field is reachable for repositioned charter aircraft from nearby bases. The closest alternate fields are Port Alexander Seaplane Base (PTD, 8 nm), Point Baker Seaplane Base (KPB, 34 nm), and Port Protection Seaplane Base (PPV, 35 nm). The field has a single 3,000-foot unpaved runway, long enough for charter aircraft up to turboprops.
Trip costs from PWR are driven by the aircraft category flown and how far it must reposition. Browse operators flying from the area or estimate a trip cost from PWR to plan your flight.

Common questions
- What size private jets can use PWR?
- Port Walter Seaplane Base's longest runway is 3,000 ft, which typically supports charter aircraft up to turboprops. Lighter classes (turboprops, light and midsize jets) operate comfortably; confirm exact performance for a specific tail with the operator, since balanced-field length shifts with weight, temperature, and elevation.
- What is the longest runway at PWR?
- Port Walter Seaplane Base has one runway; the longest measures 3,000 ft.
- What is the nearest major airport to PWR?
- The closest alternate is Port Alexander Seaplane Base (PTD), about 8 nm away, followed by Point Baker Seaplane Base (KPB) at 34 nm. Operators often position aircraft between these fields depending on ramp space and availability.
- How long is a flight from PWR to major cities?
- Typical block times on a midsize jet: Anchorage about 1h 42m (556 nm), Seattle about 2h 2m (703 nm), Jackson Hole about 3h 10m (1,189 nm). Faster classes trim these times; add positioning and taxi for the real schedule.
