It is the first time Landround has offered a two-for-one offer on American flights, however the company has enjoyed success with their single American flight promotions, which initially ran on Time Out's Paris and London guides.
Guide buyers are offered the chance to claim the extra flight to New York, Boston or Washington DC by completing the form in the back of the promotional guide and returning it to Landround to claim their voucher.
The two-for-one offer is available through a number of retailers including Waterstones, Borders, Ottakar's and Selfridges and will also feature on Time Out's Barcelona and New York guides, available from April 2005.
Tina Mills, sales director for Landround, said: "The Time Out promotion offers an extremely high-value reward to customers for a relatively low purchase.
"We are delighted to be working with Time Out and expect this to be a very popular promotion."
