d.patel Having sat in 1K and 5K on the Q Suite 777-300ER on the same route, there was no significant difference between the two that I noticed. Certainly no curvature issues which noticeably impacted row 1 and both experiences were enjoyable. I was travelling with 'she who must be obeyed' in 2J and 6J respectively and the lack of a window in 6J made that journey claustrophobic for her. We have upcoming trips on the same aircraft type later this year and we've opted for 1K and 2J again. Tried and tested IMO.
