Interesting report! Very lucky to get those four F flights for virtually nothing.
I am never impressed with UA's catering in trip reports, and this was no exception. Serving a PDB in a plastic cup in F (or J) is simply not acceptable. I'm also not a fan of cart service in F, but I thought in this trip report the sundae cart looked quite good!
The UA F lounge at JFK is certainly a far cry from the BA CCR, or even their recently refurbished F and J lounges.
However, for the virtually nothing paid for the trips I think they would have been four very enjoyably flights!
You do need to sleep more though, you know
