What is the aircraft and seating configuration (e.g., 1-2-1 or 2-4-2)? It's possible that UA is still loading the domestic 772HD (with 2-4-2 seating up front) on certain routes way in the future; I think those seats might be colored orange on the seatmaps shown in the app and on the website (as opposed to dark blue for true Polaris 1-2-1 seats).
