Delta Air Lines customers will begin receiving upgraded amenities in Economy Comfort including complimentary pillows, blankets, and food options on all flights from New York’s John F. Kennedy International Airport to Los Angeles International Airport, San Francisco International Airport, and Seattle-Tacoma International Airport beginning June 4.

Economy Comfort starts at $99 per flight segment.

Economy Comfort customers will receive a complimentary pre-set pillow and blanket on their seat while they board the aircraft. After boarding, Economy Comfort customers will be offered a Delta sleep kit, including eye shades and ear plugs, as added amenities. During flight, Economy Comfort customers will enjoy complimentary Luvo snack wraps and a full-size bottle of water for all flights and Luvo frozen yogurt bars as a mid-flight snack on most flights except those flights leaving the West Coast after 9 pm.

“Delta continues to invest in Economy Comfort with upgraded amenities for customers when they fly one of our transcontinental routes from New York to Los Angeles, San Francisco, and Seattle,” said Jeff Robertson, vice president–Product Development, Sky Clubs and Marketing Communications, in a release. “Adding pillows and blankets for comfort as well as Luvo wraps and mid-flight snack offerings improves the travel experience for our premium economy customers so they arrive at their destination rested and refreshed.”

As previously announced, by mid-June, Delta will also operate three newly refurbished Boeing 757 aircraft with full flat-bed seats in the BusinessElite cabin. The addition of these aircraft to Delta’s existing 767 aircraft will offer customers full access to flat-bed seats in BusinessElite on all flights between New York-JFK and Los Angeles International Airport. As additional Boeing 757 aircraft are refurbished in the coming months, all transcontinental flights between New York-JFK and Los Angeles, San Francisco, and Seattle will feature full flat-bed seats in BusinessElite by summer 2015.

Earlier this year, Delta introduced sleep kits for passengers seated in the economy cabin on long-haul international flights.
