$150 ETC for equipment swap from a 787 to a 777-2 (2-2-2 config) from IAH-SFO.
Had burned a RPU to snag a PZ fare for a middle seat on the 787 with direct aisle access for me and person sitting next to me. Equipment malfunction led to plane swap into older 777, put in a seat right next to lavatory and on the side section. Mentioned that I likely would've burned my RPU on another flight had I known the plane would've been swapped.
