Transatlantic carrier Delta Airlines has announced that it will soon be offering 180 degree lie-flat seats in its business class compartments on all its transatlantic flights departing from Heathrow. The planned upgrades will be rolled out by summer 2009 on all Delta Airlines flights to New York and Atlanta. Delta's flight services will switch to Boeing 767-400ERs, each with 40 of the new full flat seats for BusinessElite customers. The new seats will allow passengers to recline on nearly two metre long (77 in) beds in a one-two-one seating arrangement which allows each passenger to access the aisle without disturbing those around them. Delta plans to reconfigure seven of its 767-400 aircraft to accommodate the full-flat recliner seats. Further enhancements for the airline's International economy class passengers on the same routes will include on demand digital entertainment, printed menus, and free glasses of wine with their in-flight main meal and mid-flight snack. Complimentary amenity kits will also include ear plugs and eye shades. Delta Airlines' executive vice president of network planning Glen Hauenstein said: 'Delta continues to listen to our customers' requests for enhanced service in the world's major markets and we are pleased to add the consistency of 180-degree full flat beds to all Delta flights operating at the world's No. 1 business airport – Heathrow. ' It was also announced that Delta expects to offer a third daily direct flight from London Heathrow to New York JFK in 2009, which will be operated by Air France, Delta's transatlantic partner. The extra service will offer customers a greater range of choice regarding what time of day they fly: morning, early evening or late evening. Delta Airlines also operates transatlantic flights from London's Gatwick Airport, twice-daily to Atlanta and once daily to Cincinatti.
