I am scheduled on a 787 on Friday out of Chicago to DFW. Seat map just changed to only 5 rows of J with PE added. Cannot select seats on the app anymore. I was seated in 6L and was moved to 1D. I will report back if this plane is in fact in a revised configuration. Current tail is showing as N801AC. Inbound flight on this tail shows the pre-PE configuration. Definitely interesting why they made this change, unless a sub is planned.

The ORD-DFW flight after my departure is also a 788 and has the old seat map. Anyone else with this?
