I fly quite bit on Continental and as their fleet is now predominantly 737-800s I have observed that seat 8A does not have a window. There is room for one on the fuselage but the cutout simply is not there (really ticked me off when I had reserved that window seat thinking it was a good one being ahead of the wing and all). This is only on the left side, there is no corresponding gap on the right.
COA Customer Service was unable to offer an explanation as to why this is and my only theory would be that the row is in line with the turbine disc of te left eine and that the direction of engine turbine rotation would send the disc into the fuselage at that point. This would explain why it might not be necessary to have this gap on the right side…but I don’t know if that is the case with all airlines that operate this aircraft.
Anyone with any insight into this?
