Virgin Atlantic plans to boost services on North Atlantic routes while ceasing flights to Cape Town, Mumbai, Tokyo and Vancouver.

To better leverage its joint venture with Delta, the U.K.-based airline intends to add new service between London Heathrow and Detroit and boost frequencies between Heathrow and Los Angeles and New York JFK, as well as add more summer seasonal service from Heathrow to Atlanta and San Francisco and additional winter service between Heathrow and Miami. Virgin also will pick up a daily flight between Atlanta and Manchester, U.K. that has been operated by Delta. Meanwhile, service to Tokyo Narita and Mumbai will end on Feb. 1, 2015, and summer seasonal service to Vancouver won't resume next year. Winter seasonal service to Cape Town will operate as planned until April 2015 but won't renew in the winter of 2015/2016. "Transatlantic flying has always been at the heart of our network and our most financially successful region," according to a statement from Virgin Atlantic chief executive Craig Kreeger, adding that the network changes "play to our strengths."
