About 1,350 flights are expected to be added to connect Haikou with major tourist cities, including Shanghai, Guangdong province's Guangzhou and Shenzhen, and Hubei province's Wuhan. Meanwhile, about 180 flights are scheduled to resume, the airport says.
Chongqing, Shaanxi province's capital, Xi'an, Yunnan province's capital, Kunming, and Zhejiang province's capital, Hangzhou, are expected to be favorites of tourists planning trips lasting three to five days, Peng predicts.
Northwestern destinations also stand out among searches.
The early September, searches for travel products in Northwest China surged by 475 percent month-on-month, Trip.com reports.
The Tibet and Xinjiang Uygur autonomous regions, and Qinghai and Gansu provinces topped the search list and were especially favored by tourists from Shanghai and Guangdong.
Deserts, camel rides, danxia landforms and historical sites along the Silk Road are among the biggest draws for northwestern China, the agency says.
Most travelers are looking at five-day interprovincial trips in the region.
