The online travel agency has struck what it calls Gold Label partnerships – a variation on the white label system – to provide full search and booking facilities in the five sites.
The deals mark the end of a successful first year for the site following its launch in late-2006.
Isango has also struck a deal with Zoom Airlines to provide similar functionality on the carrier’s website.
The partnerships with WAYN, Teletext and the other sites will ensure the existing branding is retained but with full Isango product lines and call centre support.
Zoom Airlines sales and marketing manager, Kurtis Dolinki, said: “Zoom Airlines is looking forward to working with isango! as our Tours and Activities partner.
“We’re confident that their many exciting experiences in our top destinations will be of great interest to our customers and we are pleased with both the customised, branded look of the solution they have built and their ongoing creative support with cross-sell and promotional initiatives.”
