I just spoke with an Idine CS Rep. She says the employees only recently found out about the changes. She explained that it is a corporate decision in response to "changes made by the airlines". I told her I thought the only change there may be is a higher cost to buy the miles. She didn't seem to understand how that part works.
She said that she has only received negative feedback and expects a huge amount to come. The Rep offered to record my comments which are then sent to a department that tracks all of them. She encouraged you all to call. Here is an appropriate #:

Maybe if we all committ to call and each get a few relatives and friends (who loved this program) to call we can make a difference. There have been many success stories on FT where we successfully battled such "enhancements". Delta and USAIR come to mind.
