I flew FCO-CLT on a 332 in Envoy with the suites. Was very pleased with them.
Service was a little under what I've grown accustomed to on LH but was still fine.
Food was a little subpar relative to LH as well, but I should remember this is a US carrier we're talking about here.
Seat was very comfortable and I managed a 90-minute nap. I am 6'5" and had to curl a little bit, but not enough to where it made me uncomfortable.
IFE, I thought, was superb.
Considering I used CP certs on a coach ticket, I was quite satisfied with the product and would certainly use it again in a similar situation.
