I was on a flight once that boarded and then we sat for almost four hours before we even took off. Even though my bag was stuffed full, all I really had to help pass the time was a bag of M&M's and a magazine. As we sat there, I saw another guy that had a carry-on bag that didn't look that full but it seemed like he had everything he needed.
Over the hours I watched him pull out things including food, drink, book and computer. He even pulled out a battery to charge his phone. Obviously he was a professional traveler who knew how to pack, unlike me. It left me wondering how much trial and error he went through to get where he was.
I saw a news article today where people had to sit on the plane for 12 hours before they even took off and it reminded me of my flight.
What tips to pack a carry-on like a pro?
