Tried the search function to no avail. I'm scheduled to travel on JL 9 ORD-NRT; currently showing the 747 configuration with Y on the second floor, not J. I have never traveled on the first floor in J, so based on seat guru I selected 27H.

No aisle seats were available in the mini-cabin, although some look like they're blocked for airport assignment. Any input, thoughts or suggestions welcome! Thanks!
