From the article :
a “once-in-a-generation” chance for
Delta Air Lines Inc. (DAL) and Air France-KLM Group to grow at
London Heathrow,
Europe’s busiest airport.
The U.K. billionaire is considering options for his Virgin Atlantic Airways Ltd., whose 288 takeoff and landing slots at Heathrow are 3 percent of the total. A buyer would be able to use the slots to add lucrative flights to U.S. and Asian business markets
Ah yes. Would these "lucrative flights" be like the daily 777 flight that Air France started from Heathrow to LAX a year or so ago, which was an absolute financial fiasco for them ?
