Gillian Tans, the COO of Priceline's giant Booking.com unit (based out of Amsterdam), has been promoted to president and "will assume responsibility for the day-to-day operations." In addition, David Vismans, who has been serving as Booking.com's front-end product director, is now the travel site's chief product officer.
Darren Huston remains Booking.com's CEO, but he'll now have an "increased focus on talent development and driving long-term growth across Booking.com and The Group."
Meanwhile, Priceline has named Ian Brown, until now the COO of U.K.-based Rentalcars.com, the unit's CEO. He replaces Rentalcars.com co-founder Greg Willis, who will now act as executive chairman.
