The next time you get a first class upgrade on Delta, you may be in for a treat: a brand new seat.

Delta on Tuesday unveiled a brand new domestic first class seat design, which offers passengers on flights within the US more privacy, more space, bigger in-flight entertainment screens, and other new features.

The seat, which Delta said it designed with Recaro and Factorydesign, will be introduced on Delta's first Airbus A321neo, which it expects to be delivered in late 2020.

"As an industry leader in innovation, we are always looking for new ways to improve the overall customer experience," Mauricio Parise, managing director of product development for Delta, said in a statement. "Customer insights were instrumental to the new design, and we spent hundreds of hours listening to customers so that we could respond with thoughtful improvements."

Premium cabins on domestic and international flights represent an increasingly important - and growing - revenue stream for airlines.

Many US airlines, including Delta, also offer complimentary upgrades to top-tier frequent flyers, on a space-available as a reward for customer loyalty. However, those upgrades have become less dependable in recent years as airlines find more effective ways to sell premium tickets and upgrades, such as by offering the chance to purchase an upgrade with miles.

While international business class seats vary greatly between airlines and planes, domestic first class seats tend to be more homogeneous, usually variations on a bigger seat than coach, a few extra inches of legroom, and fewer seats per row. There's less for designers to work with in developing new products.

That makes Delta's new seats stand out. Scroll down to check out the new seats, and to see how they compare to Delta's current first class seats and other products.
