Showers
So the Polaris Lounges with have "spa-like showers." There will be one lounge open in 2016 with others to follow in 2017. They took away the arrivals access in Europe now(with the exception of LHR).
So for this year, one lounge and probably one plane with the Polaris seats. Time to shop around for me - likely to end the year at Platinum. On balance, more has been taken away this year than added.
The timing is always interesting. Yes, the program can change at any time but so many changes have happened in the middle of a year that there's no reason to trust anything listed as a benefit.
