Alaska Airlines (AS, Seattle Tacoma International) and Virgin America (San Francisco) will complete the integration of their passenger service system (PSS) on April 25, 2018, Alaska Air Group CEO Brad Tilden announced during an annual earnings call on January 25.

"On April 25, we'll transition to a common PSS system, which will give us a single shopping, buying, flight scheduling and airport check-in system, as well as a single branded digital and airport experience. At that point, which will be just 16 months after closing, we will be through 75% of the merger work," Tilden said.

The holding also plans to finalise the co-location of both airlines' operations in the same terminals at the remaining nine airports in April. So far, Alaska Airlines and Virgin America have co-located at 22 out of 31 airports served by both carriers, including Seattle Tacoma International, San Francisco, and Los Angeles International.

As of January 11, 2018, both units have consolidated their operations onto a Single Operator's Certificate (SOC), a prerequisite for a common PSS.

An additional milestone will be reached in March when an Airbus operations control centre will be co-located with one for Boeing aircraft at Alaska's Flight Operations Center in at Seattle Tacoma airport. Alaska Airlines' jet fleet includes a total of 154 Boeing 737 Family aircraft, while Virgin America operates sixty-three Airbus A320 Family aircraft.

After the integration of PSS platforms on April 25, the group will proceed to integrate crew planning systems next.
