The free travel benefit is intended for personal use. I believe you'd find the airline... less than pleased... if they found out you were using the travel benefit for work.
The idea is that if you are working for another company, travel for them is paid for by them. You are *not* supposed to use non rev or pass travel for buisiness activity. If the airline finds out they will revoke your travel benefits. It's possible for them to not only revoke them for you but for *everyone* who gets them from her as well as limit hers to work purposes only.
Here is a quote from a major airline's non revenue travel page:
Remember, pass travel is to be used for pleasure and authorized emergency purposes only and may never be used in connection with business activity.
Nonrev travel is a big deal and it is *not* considered a right. It's given as a priviledge and at the pleasure of the airline. Abuse of the benefit will result in losing it.
