I've managed to narrow it down on 2 options:
2:
Window side, nice guys on my side, not that much bickering around me
6:
Aisle side so i can stretch my legs, Horus should offer some pleasant conversation
Uncertain:
2:
Window side, nice guys in the rows in front and behind me, I'm not going to argue with Angron but what if i irritate him?
i would avoid:
1: the guy is a jerk
3: the stench...
8: i would feel unease
5: i would be caught between Dorn & Perturabo
4: i would be too much near to Russ & Magnus
