Flying Spirit or Frontier and want to pack as light as possible? These budget airlines often don’t include a carry-on, so everything must fit in a personal item. Here’s how to make it work: Use a large compression bag for your clothes and stick to a capsule wardrobe. Test your toiletries before leaving and eliminate anything unnecessary. Pack underwear and socks in a medium compression bag and stack it on top of your clothes for more space. Bring only one hot tool—I love my straightener/curling iron duo. Pack one swimsuit and pajamas; if needed, squeeze in a second swimsuit. Wear your only pair of shoes on the plane. Store small items in front pockets to keep them organized. Keep documents and electronics in the back compartment. Use compression straps to cinch everything down. Travel light and stress-free!
