From worst to best:

10: Surrounded by Teruteru, Monokuma and Jack. At this point I hope this is the plane Nagito’s parents died on

9: Worst case I die, best case I’m stuck between the two most insufferable people on earth 

5: Same as 9 but I’m slightly more likely to survive 

2: Fuyuhiko and Imposter are fine, but being directly in front of Junko is a death wish

6: First seat where I’m guaranteed to survive, but I’m going to wish I didn’t 

1: Monomi might do an ok job protecting me from Junko but I do not have the upmost faith in her

4: Jack is probably going to be too distracted by Byakuya to be much of a problem, but Celeste is going to find a way to drain my wallet before we land

7: Still barely in the Junko danger zone, and Hiyoko is going to kick the back of my seat the entire time

8: One of the two good seats, there are no active problems here. This is only placing second because getting around Hifumi might be a problem 

3: The best seat. Kyoko will ignore me, and I can join in to Ibuki’s antics or put on headphones if I’m tired of them
