Lastminute.com has split its entire European staff into two divisions, business-to-consumer and business-to-business.
The company said the restructure will better serve its business-to-business portfolio, which Jones will build up in his new role.
Lastminute.com said that Jones will work with chief executive Ian McCaig to develop the business-to-business half of the company before taking on a new job title.
The business division contains brands including holiday autos and medhotels.com.
Lastminute.com's consumer division will now be headed by Alfonso Castellano, previously managing director for Italy and Spain.
