Several weaknesses in airline operations were identified as the causes of the RM1.3 billion loss. The most substantial factor in the losses was fuel costs. For the period, the total fuel cost was RM3.5 billion, representing a 40.4% increase compared to the same period in 2004. Total fuel cost increases comprised RM977.8 million due to higher fuel prices and another RM157.6 million due to additional consumption. In the third quarter, fuel costs were RM1.26 billion, compared to the RM1.01 billion in the corresponding period in 2004, resulting in a 24.6% increase or RM249.3 million.
