Travelzoo has surpassed 6 million subscribers in Europe, with half coming from the UK.
The European subscriber base now accounts for almost a quarter (24%) of all subscribers to the Travelzoo brand.
An additional 13% of subscribers are in the Asia Pacific region, where Travelzoo is independently owned and operated by Travelzoo (Asia) and Travelzoo Japan under a license agreement with Travelzoo.
The remaining subscribers are in North America.
Chief executive Chris Loughlin said: “We are thrilled to reach this new milestone in Europe.
“The Travelzoo brand resonates among subscribers in many countries worldwide, because it stands for quality, simplicity and trust.
“We will continue to focus on these three brand attributes as we continue to scale.”
Travelzoo publishes travel, entertainment and local deals in 11 countries.
