Zoned airline seating based on your “Parent Sympathy Level”—essentially your self-rated level of empathy for children.

Level 1—likely a parent yourself—places you closest to babies on your flight. Level 1 sympathizes with a crying child, or can coach a lousy parent into taking care of the situation. Level 3 places you furthest away—useful in case of flying with severe hangover or if you’re just generally a miserable prick.
