I think the F rewards are pretty good value and even J isn’t too bad.
Can thoroughly recommend F rewards through to Munich. Went in late May pre-Covid and we had the F cabin to ourselves.
Chef offered to make anything we could suggest, after having well & truly enjoyed the F lounge at Abu Dhabi - we weren't that hungry so left it up to the chef who came back 90 minutes later with a Hungarian biscuit offering. We couldn't let any go to waste.
At Munich, given then they threw in a chaufeured limo to your accomodation, we weren't in a rush to get off. The steward seemed slightly anxious & asked a couple of times if we needed any help. Odd we thought, until after 6 or 7 minutes as we walked to the door we saw that the entire plane's other passengers were being held back to allow us a clear run. Oops! Many unfriendly looks in our direction.
Even worse, they obviously held them longer as it was around 90 seconds before we could hear any noise behind us - we were already in the terminal and heading down before the next people appeared.
Service was impeccable (even when others sharing the cabin out of SYD) even though the SYD lounge wasn't anything to write home about (apart from the Wagyu burgers). Good use of VFF points in our view.
Coming back used SIA, visited the Private Room (for 13 hours all told - 6 hours more than long enough, but did go on half day tour of Singapore thanks to Singapore Tourist Authority).
Whilst the extra cash costs of EY are much higher than with SIA - it was good to compare what's offered. Tick another on the bucket list.
