I flew PY for the second time ever (the first time was years ago in an empty PY cabin to NRT) and it actually wasn't too bad. Ms. Boh and I sat in 12 H/K.

Normally, I'm not a bulkhead fan due to a lack of leg room, but this was fine. It was a daytime flight (AC104 - B789), but could see how the galley noise could be annoying if you were trying to sleep. No issues with lav lineup backups on this flight. Possibly more of a concern with the A/C bulkhead seats on the 789?
