I’m a big advocate of the carry-on. I’ve mastered the art of packing light to a T and like to encourage people to reap the benefits of not having to check a suitcase in. One of the biggest advantages of having your luggage onboard with you means your stuff is going where you are—no need to rely on airport staff to make sure all your gear keeps up during the transfers.
Once you arrive at your destination and step off the plane, it also saves you the waiting time at the carousel and the energy to elbow your way to the conveyor belt to grab your bag. Another perk: no luggage fees. Most companies will let you bring a carry-on plus a personal bag at no cost while with some carriers, checking a bag in will cost you extra.
