Touchdown is a broker, in effect, selling dumped capacity, sorry, spare capacity (air, sea, hotel etc) in a restricted market so as not to influence prices downwards on the open market.
To buy from Touchdown you must prove your airline and travel industry credentials. Even then, if you are not in customer contact you won't find much available in Touchdown for you; the best discounts are restricted to agency staff, reservation staff, counter staff etc etc, so that these staff will then gain some product knowledge at least, and hopefully promote the products.
Engineers get very little from Touchdown, and I imagine that back office staff fare equally badly.
