I am thinking of changing to the sun side next time. Last month, HNL-BLI redeye, the sun was brutally bright coming up in the morning. I was in 3A and it was blinding, literally. The person in 3F would not close the shade, even when asked by the FA so it was a very uncomfortable last hour of flight shielding my eyes with my hand, magazine, whatever I could find. Yeah I know, we don't see that much sun in the Pacific Northwest but I may take 3D/F next week just in case.
