Members of the Galileo European air reservations consortium could end up with substantial stakes in the United Airlines Apollo system in the US. Allegis Corp, parent of United, says that it is negotiating to sell a 35% stake in Covia, the subsidiary that owns and operates the Apollo reservation system, with British Airways Plc, KLM Royal Dutch Airlines, Swissair and Alitalia, and is looking for $350m from the sale. It is separately talking with several companies, including some of the airlines named, about selling them another 15% of Covia.
