If you go throught he booking procedure (no need to pay) and look at the seats - they give you a plan of the plane. But basically its two rows of three seats starting 1 at the front and ABC being the seats on the right as you look down the plane form the cockpit and DEF to the left from the same view. Thats the norm for most of the there flights. Where are you going from and to that will help with the type of plane.
