Same thing. Rules say no, but it happens. The same way that miles can be earned for a reward ticket. Once a FF# is on, often points are credited. The trick is getting it on and NOT getting caught as a few 1000 miles are not worth a job.
Also, with free (or near free) travel anyway, hotel benefits are much more valuable, and less likely to get fired from a internal audit
