How Alaska’s fleet changed the game
For years Alaska relied on Boeing 737s and regional jets for short-haul routes. The carrier’s acquisition of Hawaiian Airlines in 2024 altered that strategy.
As part of the deal, Alaska gained new Boeing 787-9 Dreamliners originally ordered by Hawaiian. These widebodies enable true long-haul flights to Europe and Asia.
New livery and aircraft deployment
- The London flights will use a 787-9 painted in Alaska’s upcoming international livery.
- The Dreamliners will gradually replace Hawaiian-operated long-haul services as Alaska rebrands them.
What to expect onboard: cabins and comfort
The Dreamliner cabins mirror the premium product Hawaiian introduced earlier.
- Business class: 34 lie-flat suites with sliding doors for privacy.
- Premium economy and economy layouts designed for long-haul comfort.
- Inflight amenities will be upgraded on these aircraft to match long-haul expectations.
Partnerships, alliances and business travel demand
London is one of the world’s busiest business travel markets and an important node for the Oneworld alliance. Alaska’s new route strengthens its position within that global network.
The carrier signaled a likely increase in cooperation with fellow Oneworld members, notably British Airways and American Airlines, to improve connections and codeshare options at LHR.
Booking with Atmos Rewards: tips and transfer options
Atmos Rewards — the combined loyalty program launched by Alaska and Hawaiian — is the best way to book award travel on these new flights.
- Atmos points can be earned through flying, partner activity, and credit card offers.
- Bilt Rewards transfers: Atmos accepts 1:1 transfers from Bilt, making it easier to build award balances.
- Keep an eye out for limited award inventory; business seats in summer often list at high point levels.
- Top-tier Atmos Titanium members may receive complimentary upgrades into business if seats remain unsold.
Seasonal patterns and where Alaska is headed next
Alaska’s Rome service will run during the summer season, while London will be a permanent addition to the schedule. The carrier has publicized plans to add at least a dozen long-haul routes from Seattle by 2030.
- Planned or expected long-haul markets include Tokyo and Seoul.
- Some transpacific routes are already operating under the Hawaiian brand and will transition to Alaska-branded service.
High-speed connectivity: Starlink coming to the Dreamliners
Alaska confirmed plans to install Starlink high-speed Wi-Fi on its Dreamliner fleet beginning next fall.
Access for flyers: Once activated, the airline intends to offer Starlink connectivity free to Atmos Rewards members, matching the onboard internet experience available on many Hawaiian long-haul flights.
