Don't forget though time of day issues. NRT-SIN departs NRT in the late afternoon and arrives late evening in SIN. I agree that having the kit would be nice, but let's face it, this flight isn't an overnighter or redeye. For us that live in Asia and fly UA interAsia, they're all same day flights - our equivalent of going say ORD-SFO.
I'm also nostalgic for the days of the SIN based crew...
