Alaska Airlines’ Global Reach
I’m so impressed with Alaska Airlines and their bold transatlantic steps. They are really expanding what’s possible for us travelers heading overseas.
First Flights to Rome
Imagine stepping off a plane right into the heart of ancient history! Alaska Airlines is launching its very first flights to Rome starting May 23, 2026. Starting with four flights a week during the summer, this major move connects us directly to Italy’s capital. Rome, with its delicious food and timeless ruins, is the perfect place to begin this new chapter for the airline. It makes that dream Italian vacation feel so much more within reach.
Daily Service to London
And the European adventures don’t stop there. Alaska Airlines will also be flying to London Heathrow daily starting in May 2026. They’re using a beautiful Boeing 787-9 Dreamliner for this route, promising a truly comfortable journey. London is such an essential city, a hub for culture and business alike. This new service will surely be a favorite for so many of us looking to explore the UK.
Discovering Iceland’s Wonders
For those who love dramatic landscapes, get ready! Daily flights to Reykjavik, Iceland, begin on May 29, 2026. Alaska Airlines will operate this route with a Boeing 737 MAX 8, making it easy to reach the land of fire and ice. I can already picture exploring glaciers and soaking in geothermal hot springs. It’s an absolutely breathtaking destination.
Connecting to California
It’s not all international journeys, of course. Alaska Airlines is also enhancing our domestic travel options. Starting April 8, 2026, they’ll offer daily flights to Arcata-Eureka in Northern California. This route, using an Embraer 175, is perfect for a quick escape to the stunning Redwood Coast.
