After recovering from a drop in passenger traffic as a result of the September 11 attacks in 2001 and the severe acute respiratory syndrome ( SARS ) epidemic in 2003 , the airport saw rapid growth in traffic , which hit the 30-million mark for the first time in 2004 . In March 2008 , prior to the full effect of the financial crisis of 2007 – 2010 on the global economy , the airport was predicted to handle 50 million passengers by 2012 due to the opening of casinos in Singapore and the phased liberalisation of the Asean aviation sector . As predicted , the airport surpassed the 50-million mark in 2012
