Delta Air Lines will beef up service to Europe and Asia in the spring and summer of 2011. Significant expansion is planned for Asia, where the airline has seen revenue growth of more than 50 percent in recent months. Among other routes, new twice-weekly service between Atlanta and Shanghai, China, was proposed, as well as new five-times-a-week service between Detroit and Beijing. Those routes would begin in June and July, respectively. A variety of new routes to London (Heathrow) and Paris (Charles de Gaulle) also were proposed, slated to begin between late March and early June. The company attributes the expansion to increased international business travel demand.
