To clarify this, if your seat is for example, section 305, row EE seat 16, the seat would be about 8 rows from the entrance and on the left side at the edge. 1-15 (or thereabouts, changes in certain areas due to turns etc,) and 16-30 is on the left. row A is at the front and ZZ is at the back. Ideal seats are generally lower deck 304-306/ 330-332 rows aa-ff. Upper deck you would want rows a,b,c etc. Z is at the back. Hope this helps!
