Ever fought over the AC vent on a plane? One Delta passenger did—his seatmate kept shutting his personal breeze, sparking a frosty showdown. The drama: Who gets to control the air? Turns out, there’s no official rule, just sky-high pettiness. Pro tip: Always pack a sweater or hoodie for flights. That way, you’re ready for any temperature drama, no matter who’s hogging the cold air. And if someone messes with your vent, a polite heads-up (or a call to the flight attendant) might just save your chill. #TravelHacks #PlaneEtiquette #LifeOnTheGo #Business
