Tourists will soon have the chance to be compensated financially if they encounter haze and smoggy days during their trips.

China's largest online travel agency Ctrip.com International Ltd, together with Chinese insurance giant Ping An Insurance (Group) Co of China Ltd, started to sell haze travel insurance on Tuesday, the first travel service to exploit air quality in China.

Tourists who have booked packaged tours or backpack tours via Ctrip that last between three and seven days can all choose to buy haze insurance on the website. The insurance will be available to customers even during the most popular holidays such as Labor Day.
