While the number of ticket transactions in 2015 increased 6.2%, to 155 million, total sales decreased 1.5%, to $88.3 billion. Ancillary sales continued to increase, evidenced by ARC’s reported Electronic Miscellaneous Document (EMD) sales. EMDs are used to report ancillary sales through ARC. In 2015, $19.5 million of the total sales were comprised of EMD sales, versus $3.8 million in 2014, a 410% increase. The number of EMD transactions rose from 54,442 to 236,059. ARC attributes the increase to EMD readiness on behalf of both carriers and GDSs. Source: Travel Weekly
