Yep I second the 321, especially on a night DME. Although I’m not a fan of 321s in general tbh, even the short haul config. Try getting a BoB trolley through a full one of those on a short hop to DUS.
Long haul wise, probably the Mid J. Everything’s broken and the Bunks are grim, but I guess you’re still on a 747 so there’s a bit of pride around that.
