Thanks for the help.

What is odd is that my AA provided seatmap shows 3 seats across on both sides of the aisle - and in all rows of the MCE/Coach aircraft front to back. For instance, all of the posted schematics in the recommended thread show no 11F seat, however, I am able to select it if I want. What's up with that? Still likely Oasis/Kodiak version (with general sentiment that 8A is the seat to grab in coach)?

Thanks again.
