The number of visitors to TravelSupermarket.com was down by 11% in the first quarter of the year.
Revenues also dropped by 11% in the three months to March 31.
Parent company MoneySupermarket.com said: “Market conditions continue to be challenging across the flights and hotels channels, with consumers continuing to manage their discretionary spending tightly.
“Our package holidays channel, however, continues to perform well, in part reflecting the investment made in the new channel in 2011.”
The figures came in an interim management statement from the company this morning ahead of its annual meeting.
MoneySupermarket.com described the group’s first quarter financial performance as being in line with expectations.
Internet revenues and EBITDA were 14% and 12% ahead respectively of the same period last year.
Visitors to the Moneysupermarket.com website were 15% ahead with visitors increasing across its insurance and home services arms.
The group has cash balances of £36.6 million at the end of March.
Chief executive Peter Plumb said: “We have continued to invest in both our brand and technology which should mean the group is well placed to make further progress through the course of the year.”
