Alaska Airlines Expands 2026 Domestic Network

Alaska Airlines is expanding and reshaping its domestic network for 2026 with multiple new nonstop services and a few strategic cuts. Beginning May 13, 2026, the carrier will add Portland–Baltimore, Portland–St. Louis, seasonal Portland–Philadelphia and year‑round Portland–Idaho Falls, and will relaunch daily seasonal Hollywood Burbank–Honolulu service on May 13 using Boeing 737 MAX 8s. On March 18, 2026 Alaska will begin year‑round daily Tulsa–Seattle and Tulsa–San Diego flights and start daily Ontario (ONT)–Santa Rosa (STS) service operated with Embraer ERJ‑175 aircraft. Humboldt County (ACV) will regain ACV–Seattle nonstop service starting April 8, 2026. The airline said the network changes reflect fleet discipline — including ending nonstop Austin–San Francisco next year as fewer new aircraft enter its fleet — and follow recent operational disruption after an IT outage; local traffic data show rising demand in some markets such as Portland.
