ITA operates their A321neos with fully flat beds in a 1-1 config on their CAI route from FCO. Thats a sub-3hr flight. I redeemed Virgin points for my brother to fly DXB-FCO-LCY in that cabin for next weekend, I have only read good things about that aircraft cabin.

Longest Club Europe flight I've done is FNC. Also flown TAP Business (2-3 config in J), easyjet, Jet2 and Monarch on this route since 2008. Longest ever Club Europe flight for me was in 2023, LHR-FNC diverted via FAO and returned back to LHR due to weather at FNC. 12hrs spent onboard an A320 in Club Europe including 3hrs on the ground in FAO. Wouldn't wish that upon my worst enemy. Next flight will be easyjet LGW-FNC in June.
