🏝️ The Island Hopper
The United Island Hopper (UA154 westbound / UA155 eastbound) is one of aviation's most legendary routes. A single 737 flies from Honolulu to Guam (or reverse) with up to 6 stops across the remote Pacific:
- HNL → MAJ (Majuro) → KWA (Kwajalein) → KSA (Kosrae) → PNI (Pohnpei) → TKK (Chuuk) → GUM
For many of these islands, United is the only commercial air service connecting them to the outside world. The route is a lifeline for Micronesian communities and a bucket-list flight for aviation enthusiasts.
