Always end up with the worst seat on the plane? You know, the one right next to the bathroom, with a seat back that doesn't recline and legroom that doesn't exist? We know the feeling. And so did the makers of SeatGuru, who mapped out the seating chart of every commercial plane and marked which seats to grab and which to avoid. Just enter your flight information and SeatGuru will mark which seats have more legroom, which have better luggage storage and which have the best armrests, making your flying experience just a tiny bit easier.
