Alaska Airlines offers new premium class seating

Alaska Airlines has offered a premium class section on select routes beginning in early January 2017, the company said.

The new section, which allows four extra inches of legroom, is the result of a retrofit of its all-Boeing fleet. The new section offers 35 inches of space between rows, compared to 31 to 32 inches in the main cabin.

The company said it expects nearly half of the fleet will feature premium class by the end by the end of 2016, with the balance of planes being reconfigured in 2017. A decision on when the 737-700s will be retrofitted will be announced mid-2017. Alaska will retire its fleet of 737-400s in 2017. The upgrade option will also be available on the Embraer 175s operated by SkyWest Airlines and soon, Horizon Air.

Alaska Airlines, together with its regional partners, flies 32 million customers a year to more than 110 cities with an average of 970 daily flights throughout the United States, Canada, Costa Rica, Mexico and soon Cuba.
