The improvement in baggage handling has been attributed to increased investment in technology, which has resulted in an estimated saving of USD 18 billion, it said.
The rate of mishandled bags in 2014 stood at 7.3 bags per thousand passengers, down from a peak of 18.88 bags per thousand passengers in 2007, global airlines IT solution services provider SITA said in its report today.
This decline comes despite a significant rise in number of passengers over the same time period, peaking at 3.3 billion passengers in 2014, the SITA 2015 Baggage Report said.
Observing that rising number of passengers will continue to place pressure on baggage infrastructure and processes, Violante said, "the industry cannot afford to become complacent."
