The bad congestion at the immigration gates involving about 1,000 passengers at the Low-Cost Carrier Terminal (LCCT) in Sepang yesterday was airline AirAsia's fault, the Immigration Department said.

Its director-general Aloyah Mamat said this occurred because AirAsia refused to move to the new terminal, the KLIA2, on May 2, like the other airlines, and intends to stay at LCCT until May 9.
