I was a loyal PP holder for a few years then dropped it but took it back last year. This time I took the unlimited option.
I agree that some of the PP lounges are awful. Early 2016 transit through Munich on Lufthansa being a good example. But the return via Zurich meant I could use the Swiss lounge there.
Now I’m back to Star Gold so my PP is less useful. BUT…..
I have recently flown through Singapore on SQ a lot in Economy. As Star Gold I get access to the KrisFlyer Gold lounge which is, in short, appalling and embarrassing for the airline. Especially the lack of showers and very average F&B.
But with my PP I used several other lounges at Changi Airport T3 which had decent showers and food. It made all the difference for those flights.
That said, I could have purchased entry separately to those lounges but it was great to be able to use the PP. Plus the Sofitel at LHR T5 as an arrivals lounge.
I probably won’t renew now that I’m Star Gold again but it wasn’t all bad.
