I belong to Toastmasters and I am ITCHING to do a talk to my Club on the glories of loyalty programs. But, it's a company-sponsored chapter. I travel on business only a few times a year although I've scored trips to India and Munich (and am working on getting to India again). Most of the perks I get are due to personal travel (husband and I usually go to Europe twice a year), judicious use of credit cards with hotel rewards (unfortunately I have to use the corporate MC for business) and promos I learned about on FT such as ACAQ and CTCH. I will also switch to a hotel other than the official convention hotel for meetings of my professional society in order to get points- but only if it's convenient and less than the official place.
My concern is that the presentation will somehow make people think I'm making decisions about business travel that cost the company extra to maximize freebies, and then using those perks on personal travel. So, the talk will go undone for now!
