Arrivals lounge:
You are correct. I had to sit on the left as you come in to the arrivals lounge to eat. The 'Kindergarten' chairs/tables were all taken.
Check in:
I fly JFK/LHR and have a green card. You are correct in that I PMOBP at the SSCI and always only have handluggage so must have missed the message to visit a passport check desk before going through security.
Cloud:
DOn't mean to be harsh about the cloud, but the great lights at JFK T7 died pretty quickly which I always thought was a shame. I just hope the same doesn't happen to the cloud (which is great at the moment).
