Looking at the US airline industry, considered the great hope for deregulation in 1978, it has seen the six largest companies control of the market rise from 73% in 1978 to 85% in 1987 (and increasing fares across the board). [ "Unexpected Result of Airline Decontrol is Return to Monopolies," Wall Street Journal , 20/07/1987] By 1998, the top six’s share had increased by 1% but control was effectively higher with three code-sharing alliances now linking all six in pairs.
