United Airlines plans to introduce an international premium economy cabin later this year.

In an email to customers Thursday, the carrier said that United Premium Plus will feature larger seats and more amenities than can be found in the economy cabin.

Passengers will enjoy an upgraded dining experience on china dinnerware, free alcoholic beverages, an amenity kid and a Saks Fifth Avenue blanket and pillow.

United didn't provide specifics about what planes would have Premium Plus, nor did it say when the rollout would occur. United also hasn't revealed the space between rows, the seat width and the amount of seat recline.

A United spokesperson declined to elaborate on the product on Thursday. 

With the rollout of Premium Plus, United will join American and Delta, which introduced premium economy cabins on international flights in 2016 and 2017, respectively. Both carriers offer 38 inches between rows in premium economy, which is six or seven inches more than passengers get in coach.

Most major international airlines have a premium economy cabin on long-haul flights.
