Mexico's Interjet has become the country's domestic market leader for the first time since it began operations in 2004, with a 24.8% market share, relegating Aeromexico Connect to second place.
Aeromexico Connect and the mainline Aeromexico carrier, however, still hold a combined market share of around 40%.
According to figures provided by Mexico's civil aviation authority DGAC and the airlines, 25.4 million passengers flew on domestic flights in 2011, only slightly more than in 2010 and still well below the 27.6 passengers that flew within Mexico in 2008.
Airlines including Aviacsa and Mexicana were grounded in the following two years, altering the domestic passenger market.
Interjet benefitted most from the demise of Mexicana, growing its passenger numbers by 58% to 6.3 million and taking over a share of its Mexico City International airport originating traffic. In 2010, Interjet held a 16.3% market share.
Aeromexico Connect holds a 20% market share with 5.2 million passengers and Aeromexico itself handled five million domestic passengers. Volaris came in fourth with 4.6 million passengers, although a recent big Airbus A320 order may put it on the fast track to improving its showing.
Low-cost carrier VivaAerobus is ranked fifth with 3.3 million passengers in 2011, 45% more than in 2010.
