Typhoon Sinlaku · April 2026

What Was This?

In April 2026, Typhoon Sinlaku (T2604) formed near Chuuk and intensified to Category 5 — 130 mph sustained winds, 905 hPa — cutting off Chuuk Lagoon International Airport from all commercial air service. United Airlines, the only carrier serving TKK via its island hopper milk run from Guam, cancelled all flights and evacuated its 10-aircraft Guam-based 737 fleet to safe harbors across the western Pacific.

This microsite was built while stranded at Chuuk to answer one question: is TKK flying yet? It tracked the entire fleet in real time, showing where each aircraft was parked, which ones were airborne, and when the first flight back to Chuuk might depart.

The Island Hopper

A single 737 MAX 8 flies the entire route — Guam to Honolulu one day, overnights, and returns the next. It's the only way in or out of Chuuk, Pohnpei, Kosrae, Kwajalein, and Majuro by commercial air, making each of these islands entirely dependent on that one aircraft.
