NEW YORK ( TheStreet) -- All-coach airline JetBlue Airways ( JBLU) announced it is adding a business-class cabin that will include 16 lie-flat seats on flights between New York and Los Angeles and San Francisco. The 16 premium seats will include air cushions with adjustable firmness and massage capabilities, a 15-inch television and a "wake-me-for-service" flight-attendant indicator. They will measure 6 feet, 8 inches when reclined into full, lie-flat position. Four of the 16 seats will have doors and will be dubbed "private suites." JetBlue said 11 of its new Airbus A321 planes will feature the seats in the second quarter of 2014. Planes that include the new seats will accommodate 143 passengers in coach. JetBlue hasn't yet announced the price of the new premium seats. Competitors United Airlines ( UAL), American Airlines and Delta Air Lines ( DAL) have all been implementing seats that can fully recline on their transcontinental flights.
