The number of bookings for overseas trips from China jumped more than 11 times ahead of the three-day Dragon Boat Festival holiday from a year earlier, with Southeast Asia remaining the favorite holiday destination for Chinese tourists.

Bookings with online travel agents for June 22 to 24 surged more than 12-fold from a year ago, data from China's biggest Trip.com showed. Bookings through Alibaba-backed travel platform Fliggy soared 16 times, according to its data.

Sixty-five percent of outbound travelers are headed to Bangkok, Phnom Penh, Kuala Lumpur, Manila, and Singapore, data released by travel agency Ly.com showed.

But the average spent on outbound travel products fell by about 10% compared with that forked out over this year's Labor Day holiday, according to Fliggy.
