Agreed, only because 72K is closer to the lavs. Although with the new layout (facing towards the windows) this isn't much of a problem - not like that one horrible BE seat on the 777 that faces directly at the lav door.

Not sure if this has been mentioned yet, a pilot showed me the other day on the way back from NGO, both 72K and 73A have their own storage lockers. Yup, it's pretty awesome, especially for those of us who use rollerboards that don't fit in the UD bins. You can't see the door in nypd's picture, but it would be on the left side of the pod for 72K (in his pic), and on the right side if you're in 73A. Lots of room in there for a large carry-on.

Also note that the new UD config has opened access to a large closet behind 80K that was blocked by the old BE seats. This is now easily accessible and can fit a few suitcases.

Lots of new storage spaces on the UD for large carry-ons, which avoids confronting pissy FAs who want the closet by the stairs all to themselves.
