The world's low-cost carriers (LCC) and airlines not part of the global alliances have taken market share away from the leading global groupings again this month, continuing a theme of recent months. Over the past 12 months, LCCs have increased their share of global aviation (in terms of seats per week) from 22.9% in Aug-2010 to 23.8% in Aug-2011, while the un-aligned carriers have risen from 27.6% to 28.8%. Over the same period, Star Alliance's share has fallen 0.9 ppts to 23.1%, while oneworld has lost 0.8 ppts to 10.2%. SkyTeam has seen its share drop 0.3% to 14.1%, according to Innovata schedule data.
