But Virgin Atlantic argued that British Airways and American Airlines would still control 100% of the international routes in and out of Dallas, 80% of those in Boston, 70% of those in Miami and 68% of those in Chicago.
This from the same group that owns a majority stake in Virgin Trains, which enjoys the benefits of a "moderation of competition" clause in their franchise, preventing other train companies from stealing passengers from them by offering competing services
