Agree on the F service. The meal time cutoffs are ridiculous and the snack is tiring and appearing on way too many flights, including some long hauls.
Remember when PS redeyes used to have special snacks like fruit and cheese? No more.
My recommendations in order of priority:
1. The staggering increase in Delays/cancellations/IRROPs meltdowns
2. 1K no longer singled out for loyalty, now just "part of the elites"
3. Upgrade priority/TODs/shenanigans (Gov. fares trumping elites, mileage kettle trumping elites)
4. F Class Meals / cut off times
5. Customer service response times via email
Let us know how the call went. Thanks for the opportunity for us to give some input OP
