Delta Airlines Business Class Seats

The signature feature of modern Delta Airlines business class seats is the Delta One Suite. The first fully closing door business-class suite ever introduced by a U.S. airline (debuted in 2017 and still unmatched by American or United in 2025).

Key features include:

• Direct aisle access in a 1-2-1 layout on A350-900, A330-900neo, select 777-200ER/LR, and updated 767-400ER planes.

• Full-height sliding door for complete privacy.

• Lie-flat bed: 76–82 inches long (up to 6'10" on the A350) and 21–24 inches wide.

• Westin Heavenly bedding: recycled-plastic duvet, two pillows, and a plush mattress pad.

• Entertainment: 18-inch HD touchscreen with Delta Studio, mood lighting, and noise-canceling headphones.

• Convenience: large tray table, universal power, USB-A/USB-C ports.

• Storage: You also get practical storage spaces like a shoe compartment, a laptop slot, a water-bottle holder, and a built-in mirrored vanity.

On domestic transcontinental routes (JFK/SFO/LAX/BOS to LAX/SFO/SEA), Delta uses domestically configured 757s and A321T aircraft with true lie-flat reverse-herringbone seats. These are marketed as Delta One, but do not have doors.
