Will a 30L bag count as a personal item?

Usually, no. Most airlines define a personal item as something that fits completely under the seat. A 30L bag is often too tall or wide. Stick to 25L or less to be safe.

How do I handle laundry?

Plan to wash your clothes in a hotel sink or local laundromat every 4-5 days. Pack a small packet of travel detergent.

Travel With Only a Personal Item

To travel with only a personal item, you must use a bag that fits under the seat in front of you—typically 18x14x8 inches or smaller. You will need to pack a minimalist capsule wardrobe and utilize compression packing cubes to maximize the limited space.

Choose the right bag. Select a soft-sided backpack designed for travel (around 20-25 liters) rather than a rigid suitcase. Ensure it has no external frame and conforms to strict airline dimensions to avoid gate-check fees.
Build a capsule wardrobe. Limit yourself to 3 tops, 2 bottoms, 5 pairs of underwear, and 1 pair of comfortable walking shoes (wear the bulkiest pair). Stick to a neutral color palette so everything can be mixed and matched.
Use compression cubes. Roll your clothes tightly and place them into compression packing cubes to remove excess air. This saves about 30% of the volume in your bag.
Consolidate toiletries. Use solid toiletries (shampoo bars, stick deodorant) to bypass the liquid limit. If you must bring liquids, use 3-ounce silicone squeeze tubes and keep them in a clear, accessible pouch at the very top of your bag.
