Hawaiian Airlines and Alaska Airlines transitioned to a shared passenger service system on April 22. The two airlines will now use the same Sabre PSS used by Alaska, according to the airline’s post on Wednesday.
Hawaiian noted, “The combined company’s shared PSS serves as the central reservation technology that connects the digital tools and programs used by guests and employees; from websites, mobile app, Atmos Rewards and Huaka‘i by Hawaiian loyalty programs, to airport kiosks and reservation records.”
In December 2023, both airlines announced that Alaska would acquire Hawaiian in a deal valued at approximately $1.9 billion. The deal was completed in September 2024. The deal also included $900 million of Hawaiian’s net debt.
The Most Complex Integration
According to Hawaiian and Alaska spokesperson Alex Da Silva, the integration between the two airlines involved four major milestones.
First is the launch of a single loyalty program, Atmos Rewards. Next is receiving a single operating certificate (SOC) from the Federal Aviation Administration. Then there is the implementation of a single passenger service system. And lastly, is the joint collective bargaining agreements from the two airlines’ unions.
One Shared Passenger Service System
Da Silva said in an email, “This is the biggest and most complex integration project in our combination, one that involved hundreds of Alaska and Hawaiian airlines employees collaborating for over a year.”
He added, “We appreciate our guests’ patience during this period as we worked to move to a single PSS, and we look forward to delivering a smoother and more enjoyable travel experience for our guests.”
Passengers from both Alaska and Hawaiian can now manage their trips through a single Alaska Hawaiian mobile app.
On Thursday, Hawaiian also joined the oneworld Alliance. The oneworld Alliance includes member airlines serving more than 1,000 destinations in 170 countries worldwide. This also allows Atmos Rewards members to earn and redeem points across all oneworld airlines.
