Southwest Airlines remains easily the largest LCC, while Lion Air and Jetstar have each climbed the LCC top 10, to sixth and seventh places respectively, overtaking Westjet. Atlanta Airport (just) remains the world's largest, ahead of Beijing Capital Airport, in terms of seat throughput for the week, but this ranking seems certain to reverse in 2013.
The biggest movers in the overall World Top 50 list include Turkish Airlines, which jumped seven places to rank 15th globally, while Indonesian carrier Lion Air vaulted eight places to enter the global Top 40 for the first time. Iberia and India's Jet Airways fell four and seven places in the 2012 rankings, respectively.
Global Airline Alliances collectively grew capacity at higher than the world rate, with SkyTeam expanding fastest of the three majors, althoughStar Alliance remains easily the largest.
