UA picked probably the best 1-1 seat for Polaris. It will also be the 737-10 MAX Polaris seat for TCON flying. I really wonder why UA isn't just using more of the A321neo for TCON flying, given the fuselage width, and just having one standard configuration for the 737-10 MAX. The aisle upfront is going to see on the awfully narrow side. If I am not mistaken, the standard 737-10 MAX configuration will be 20F/64Y+/104Y.
