ONLINE travel services were the subject of 1,900 complaints in the first three months of the year, the Shanghai Consumer Rights Protection Commission said yesterday.

The total was almost four times the figure for the equivalent period of last year and accounted for 80 percent of all grievances related to tourism, it said.

“Just as the market for online travel services has boomed, so too has the number of complaints,” said Tang Jiansheng, the commission’s deputy secretary-general.
