Australians had travel on the brain over the January holiday break, with a huge increase in visitors to online travel websites, according to Nielsen's digital ratings for the month. More Australians visited cruise line websites - 20 per cent more in fact - than any other travel category throughout January 2017. Princess Cruises led the cruising category of websites, reaching almost 600,000 readers, followed by Royal Caribbean Cruises and P&O Cruises. OTAs of Booking.com and Trivago took the leading spots, pipping Airbnb at the post, although the room sharing platform still managed to grow by 26 percent in audience ratings. In airlines, Qantas was the most popular website to visit, with four million readers in January followed by its LCC airline Jetstar. Find out more.
