Delta One, Delta Air Lines’ premium service featuring lie-flat beds, will be added on six new domestic US long-haul routes in spring 2018.

The premium service will be offered on flights between Boston and Los Angeles, New York/JFK and San Diego, JFK and Seattle, and JFK and Las Vegas beginning on May 1, 2018.

Delta One also will be offered on one daily flight each between Atlanta and Honolulu, and Minneapolis and Honolulu, beginning on April 1, 2018.

Delta Sky Miles Medallion Members will be eligible for unlimited day-of-departure upgrades to Delta One cabin on all domestic flights, the airline also announced.

The new premium service, which takes the place of First Class on these flights, was rolled out beginning in 2016 on long-haul international flights and transcontinental flights between JFK and Los Angeles, JFK and San Francisco, Washington, DC (Reagan) and LAX, and Boston and San Francisco.

Widely viewed as Delta’s response to JetBlue’s popular Mint service, Delta One includes 180-degree flat-bed seats, chef-curated menus with seasonally rotating wines selected by Master Sommelier Andrea Robinson, In-seat power and USB outlets, seat-back entertainment screens, noise-cancelling headsets, and a TUMI amenity kit with Kiehl’s products. Travellers also will get complementary Delta Sky Club access, Sky Priority check-in, security, and baggage handling, priority boarding, and – in Los Angeles – Delta ONE at LAX check-in service.
