Alaska Air buying Virgin America

Seattle-based Alaska Airlines is buying rival Virgin America in a deal worth more than $2 billion.

The goal, according to the company, is to create “west coast premier airline.”

Alaska Air will pay $57 in cash per Virgin share. That’s a 47 percent premium to its Friday closing price of $38.90.

The companies put the transaction’s value at about $4 billion, including debt and capitalized aircraft operating leases.

Alaska Air said Monday that the deal will expand its route network to include 1,200 daily departures. The airline is currently the sixth-largest U.S. carrier by traffic and serves 90 destinations in the U.S., Canada and Mexico. This deal gives them a bigger presence in San Francisco and Los Angeles, two coveted gates at Dallas Love Field, and more transcontinental service.

The combined business will be based in Seattle.

The deal marks a shift in the size of consolidations within the airline industry. For more than a decade consolidation swept through the major players, reducing the largest nine carriers in 2005 to four airlines by the end of 2013. The Alaska Air buyout of Virgin America indicates that consolidation has shifted to smaller players.

Virgin America got off the ground with support from minority owner Richard Branson and began flying in 2007. It went public in 2014 and while it has experienced growth in Dallas and added new service to Hawaii and Denver, the airline was having trouble getting enough takeoff and landing slots at busy New York airports. Its limited size and schedule made it difficult for the company to compete with bigger carriers for lucrative business travelers.

Both companies’ boards have approved the transaction, which is expected to close no later than Jan. 2, 2017. It still needs approval from Virgin America shareholders.

Virgin America’s stock jumped more than 33 percent in premarket trading.
