UK-based Virgin Atlantic Airways will reconfigure its route network by cutting services to Asian and African destinations in favor of a greater concentration on North Atlantic services.

The changes are the latest harmonization of services between Virgin Atlantic and Delta Air Lines, which holds a 49% shareholding in Virgin Atlantic.

Under plans announced Wednesday, Virgin Atlantic will offer an additional daily frequency on services between London Heathrow and New York JFK (5X-daily), Los Angeles (2X-daily), Atlanta (2X-daily in summer season), Miami (2X-daily in winter season). It will also increase Heathrow-San Francisco services to 5X-weekly.

Virgin Atlantic previously announced it will start a new Heathrow-Detroit service in 2015. It will also take over transatlantic joint venture partner Delta’s current daily service between Atlanta and Manchester.

To create the required capacity for these increases, Virgin Atlantic is ending services from Heathrow to Tokyo Narita and Mumbai (Jan. 31, 2015), its summer seasonal service to Vancouver (Oct. 11) and winter seasonal service to Cape Town (April 27, 2015).

The carrier said it would be eager to restore services to those destinations “if Heathrow gains its long overdue expansion. The intended changes will enable Virgin Atlantic to better utilize its fleet by flying routes which deliver maximum profit or strategic importance,” the airline said. It has been loss making in recent years, but hopes to return to profitability by the end of 2014.

“Transatlantic flying has always been at the heart of our network and our most financially successful region,” CEO Craig Kreeger said. “Today’s announcement allows us to play to our strengths and focus our network on routes between the UK and US, as well as other critical global destinations that are most important to our customers.” 

As part of improving its customer service, it plans to invest £300 million ($495 million) between now and 2018 in a series of enhancements including a new Clubhouse lounge at Los Angeles, fleet-wide Wi-Fi roll-out and refurbishments to its Airbus A340s until they are replaced by new types.

Meanwhile, Delta announced Wednesday it will launch daily Manchester-New York JFK service from June 2, 2015 as it increases its network between the UK and North America. The Atlanta-based carrier will also begin flying its first nonstop service between Heathrow and Newark from March 29, 2015.

Delta’s new Newark operation is part of a network update by Virgin Atlantic where it will operate one of Virgin’s two Newark services while Virgin Atlantic will start its first daily nonstop Manchester to Atlanta service.

“The UK is a key market for us and building our connections to the United States is a top priority,” said Perry Cantarutti, Delta SVP-Europe, Middle East and Africa.
