When packing a carry-on for travel, start by selecting versatile clothing that can be mixed and matched to maximize space. Roll your clothes to save room and reduce wrinkles. Pack lightweight, wrinkle-resistant fabrics and layer for warmth instead of bulky items. Use packing cubes or compression bags to organize your items and keep everything compact. Make sure to pack toiletries in travel-sized containers (under 3.4 oz) and place them in a clear, resealable bag for easy access during security checks. Don’t forget essential items like chargers, medications, and a small travel pillow. Lastly, leave a little extra space for souvenirs or items you may pick up along the way. Keep valuables, like your passport, wallet, and electronics, in an easily accessible pocket or compartment.
