Global spending in five-star hotels rose by an average of 14 per cent during the year to October 2010 when compared to 2009.
The figures from American Express Business Insights (AEBI) suggest that confidence has returned to wealthy consumers and business travellers.
Sujata Bhatia, vice president of Business Insights at American Express, said increased consumer confidence among wealthy travellers is a positive signal that economic conditions are improving.
"While we've not returned to pre-recession levels, the strong growth in spending in five-star hotels indicates that more affluent consumers and business travellers are regaining confidence," she said.
