On my recent trip to NRT with my other half we had 62A/B on both legs of the trip. Having sat downstairs on many occasions I much preferred the UD.

A bonus of having facing seats rather than adjacent ones is the ability to raise the dividing screen if you get tired of your companion interrupting your watching of the IFE to tell you what's happening in the film she's watching. She took the hint pretty quickly after that.

I'm sure she'll start speaking to me again sometime soon...
