United has just killed business RTW awards on Star Alliance

UA has changed its award pricing model so that no longer have a business "saver" award, all flights are priced on a variable scale where the cheapest flight can be less than 25% of the most expensive. This means the other Star Alliance booking engines can no longer see a saver fare even if the cheapest of the variable fares is at saver pricing.

Withough transiting the US there is little or no chance of being able to do a sensible RTW itinerary - although you can travel home from NY on Singapore Airlines via Frankfurt and Singapore.

UA mileage plus commentators see this as a devaluation which it probably is, but when it is not a devaluation it still destroys the members' value as that previously excellent way of using points is now only a memory.
