ATLANTA, Oct. 29, 2013 /PRNewswire/ -- Delta Air Lines (NYSE: DAL) will debut three updated Boeing 757 aircraft on the transcontinental route between New York's John F. Kennedy International Airport and Los Angeles International Airport beginning July 1, 2014, with tickets now available for purchase. These will be the first 757 aircraft in service to feature Delta's previously announced upgrades which will include full flat-bed seats in BusinessElite on transcon flights between New York-JFK and Los Angeles, San Francisco and Seattle. All transcon flights on these routes will feature flat-bed seats by summer 2015. The aircraft will include 16 full flat-bed seats arranged in a 2-2 configuration in the BusinessElite cabin. Each seat is 20 inches wide – expandable up to 22 inches – with an average bed length of 76 inches. Cabin mood lighting and high definition 16-inch video monitor at each seat will further improve the onboard experience. "Delta customers traveling from New York and Los Angeles continue to tell us that the comfort of full flat-bed seats is a meaningful element of their travel experience," said Tim Mapes, senior vice president–Marketing. "This expansion demonstrates our commitment to listening to what customers value most and then acting quickly to provide it." The addition of flat-bed seats to the 757 transcon fleet will complement Delta's existing Boeing 767 transcon flights which already feature flat-bed seats for a total of eight daily flights on the route. Customers will enjoy a gourmet three-course menu from renowned chef Michael Chiarello paired with wine from Master Sommelier Andrea Robinson's specially curated Delta Winemaker Series, Westin Heavenly In-Flight bedding, a Tumi amenity kit featuring skincare products from Malin+Goetz, a noise-reduction headset, Starbucks coffee and sparkling wine round out the BusinessElite experience. Modifications to Delta's 757 transcontinental fleet will also include changes to the economy cabin, with the addition of Economy Comfort seats. The 44 extra-legroom seats offer 35 inches of pitch and 50 percent more recline in a 3-by-3 configuration in addition to 108 standard economy seats. All seats in the economy cabin will feature a slim-line design for more personal space, an adjustable headrest, a nine-inch video monitor and standard 110v and USB power ports available at every seat.
