US approves expanding Delta venture with European airlines

The Transportation Department is granting antitrust immunity to let Delta expand a joint venture with Air France, KLM and Virgin Atlantic

Some consumer groups argued that the joint venture will reduce competition and lead to higher fares. New York-based JetBlue Airways, which plans to begin flights to Europe in 2021, said U.S.-Europe service is dominated by three big airline alliances — it wanted the other carriers to give up takeoff and landing slots in London and Amsterdam.

The Transportation Department says it will protect competition.
