As a member of 15 frequent flyer programs - way too many but it just happened - I have been using accrued points in programs with which I can no longer be bothered, where my business appears not to be appreciated and am consolidating and switching loyalty as part of reducing to around three or four so that I at least cover Star Alliance, oneworld, and Sky Team. Using MileagePlus points has been a real challenge even on Star Alliance. For my major destination of interest from home in New Zealand (France), there is also no way either to book anything other than economy. I have been able to use up points on some regional flights in New Zealand and Trans-Tasman but it proved totally impossible for hotels and rental cars. I still have to use up 35,000 points.
