Mobile transactions accounted for 12.5 percent of total travel sales in 2014.
According to Euromonitor’s WTM Global Trends Report 2015 report for the travel industry, a total of $96 billion of travel sales were conducted on mobile globally in the year.
Western Europe had the highest spend on travel through mobile, with around $33-34 billion of sales on mobile in 2014.
This was ahead of North America’s total at around $30-31 billion, and Asia-Pacific at around $20 billion.
Euromonitor forecast that mobile sales would see 22 percent compound annual growth between 2014 and 2019.
The future would also see a growth in personalised services.
"A gradual shift to one-to-one marketing in travel will be evident, with each consumer treated in a different way in terms of the overall marketing mix including pricing," the report reads.
"Beacon technology is expected to take off in the next few years as a powerful tool to provide personalised experiences to consumers on the go."
