All scheduled AirAsia departures from Kuala Lumpur use the Low cost carrier terminal. AirAsia had abolished its fuel surcharges on November 2008, but, due to rising oil prices, the fuel surcharge was re-introduced in May 2011. During 2007, passengers from 'The Barrier-Free Environment and Accessible Transport Group' protested against the airline over its refusal to fly passengers who were completely immobile. They claimed that the disabled were discriminated against when booking tickets online; the CEO of the airline denied that it turned away wheelchair-using passengers. In 2012, AirAsia was the subject of a boycot campaign in Vietnam when it mistook Chinese qipao as Vietnamese traditional clothes in a photo on Facebook. AirAsia later apologized for its mistake.
