I did EWR-LIS-EWR last year in C. Outbound was on an A310 which had the lie-flat seats which are fine - kind of a Greyhound bus version of a SpaceBed. Return was on an A310 which did not have the new seats - it had lounger seats that would have been embarrassing 10 years ago, let alone now. I don't know if that aircraft is still lurking out there, it was the last one without the new seats I believe.

I oddly found TAP intra-Europe in C to be better than average with quite decent food and good service, distinctly superior to the trans-Atlantic flights.
