It may be true that employees are manipulating the system to get additional fare cost miles through the TWA system, but FF programs in general have to be one of the biggest sources of inefficiency in corporations with employees who travel anyway. Admit it, haven't we all taken a connecting flight instead of a non-stop at times because we can't get there directly on the airline we want to accumulate our miles on? And that lost time is time when you are not operating at peak efficiency for your company. I would venture to say that this is a far greater loss of corporate value that the minor additional cost that someone might try to get out of a TWA higher cost fare to get more FF miles.
