Alaska Airlines said it has announced plans to roll out a premium class section.
Beginning in late 2016, the new upgrade option will provide more legroom and other perks to customers.
Customers who upgrade will get priority boarding and enjoy three to four inches more legroom compared with a standard coach seat.
Upgrade pricing and details on the included amenities will be announced closer to customer availability.
Alaska said it plans to retrofit up to 60 aircraft with the section by the end of 2016 and the remainder of its 737-800, -900 and -900ER fleet by the end of 2017.
Alaska Airlines, a subsidiary of Alaska Air Group (NYSE: ALK), together with its partner regional airlines, serves more than 100 cities through an expansive network in the United States, Canada, Costa Rica, and Mexico.
