Transfers, including both private cars and shuttle services, are to be integrated into a number of areas on the sites including the travel extras and flight confirmation pages.
Holiday Taxis’ sales and marketing director Russell Parr described the deal as a great fit for both parties and anticipated the partnership would grow further during the course of the year.
The plan is to support the partnership with both online and offline marketing activity.
XL.com managing director Martin Lock said: “Holiday Taxis is a great product to offer XL.com customers ensuring they have a smooth and hassle-free transfer to and from their hotel.”
Holiday Taxis is targeting two million passengers in 2008 – double last year’s figure.
