United moving ahead with making business class more sleep-friendly

United is making progress adding its new business class cabins to wide-body jets, and plans to introduce a plane with its new Polaris seats every 10 days until it completes cabin retrofits at the end of 2020, executives said Wednesday. The new seats, introduced by United CEO Oscar Munoz in June 2016 began flying last year, but have not been installed as quickly as customers would like. They’re now on only 19 aircraft, according to the carrier’s website, though United executives have said the program is on schedule, despite some early snags because of manufacturer delays. In addition, executives said Wednesday United soon will begin introducing its long-haul, premium economy product, called Premium Plus, to long-haul jets. While that project won’t finish until the end of 2020, United said it could begin selling premium economy late this year in advance for 2019 flights. The product should begin appearing on aircraft this summer, but at first, United will only let passengers buy up to it at the last minute.<br/>
