Really appreciated the leg room despite purchasing an economy ticket. Appreciated the extra complimentary wine. Nice touch. Was given immediate support without asking at check in, at the machine!! Ottawa's boarding was very organized with distinct rows in waiting room. Allowed for the main hall to not be blocked by people waiting to board.
