Pro Tips for Carry-On Travel
- Choose a 40L “personal item” sized bag if budget airlines. Fits under seat = free.
- Wear heavy items on the flight. Boots, sweaters, winter coats. Saves bag space + weight.
- Pack heaviest items at the bottom for easier rolling + stability.
- Compression cubes (Eagle Creek, Peak Design) save 30-40% space.
- Empty water bottles through TSA. Fill after security. Save $5-8 on bottled water.
- Liquids in 3.4oz (100ml) containers only. All fitting in 1 quart-size clear bag.
