The "Survival Kit" in Your Cabin Bag

The Carry-On "Survival Kit"

The goal of a survival kit is to keep you functional for 24 to 48 hours if your checked luggage vanishes or you are stranded in an airport overnight. To stay compliant with aviation security (like TSA or EASA), this kit prioritizes multi-use items and avoids restricted liquids or sharp objects.

1. The "Fresh Start" Hygiene Pack

Keeping clean helps regulate your mood and energy during travel stress.

• Solid Toiletries: Swap liquids for solids to bypass the 100ml (3.4oz) rule. Look for solid shampoo bars, toothpaste tabs, and stick deodorants.
• Compressed "Coin" Towels: These tiny discs expand with a drop of water into a durable face cloth.
• Travel-Sized Wet Wipes: Essential for "sink showers" and cleaning sticky surfaces.
• Spare Underwear & Socks: The absolute minimum clothing requirement. Merino wool is recommended as it resists odors and dries quickly.

2. The Tech & Power Core

In the modern world, a dead phone is a safety risk.

• High-Capacity Power Bank: Ensure it is under 27,000mAh (100Wh) to meet international flight regulations.
• Multi-Country Plug Adapter: Choose one with built-in USB-C ports so you can charge multiple devices from one outlet.
• Physical Backup: A small notebook and a pressurized ink pen (like a Fisher Space Pen) that can write at any angle or on greasy paper.
• Charging Cables: Keep these in a small cord-organizer bag to prevent "cable spaghetti" in your pack.
• Pen:

3. Health & Comfort Essentials

• The "Mini-Med" Tin: Use a small mint tin to carry a few tablets of:
  • Painkillers (Paracetamol/Ibuprofen)
  • Antihistamines (for unexpected allergies)
  • Anti-diarrheal medication
  • Melatonin (to help force a sleep cycle shift)
• Lip Balm & Small Moisturizer: Cabin air is a desert. Ensure these are in your clear "liquids" bag.
• Noise Buffers: High-quality silicone earplugs and a contoured eye mask.

4. The Adventurer’s Substitutes (Safety Compliant)

Since you cannot carry knives or large multi-tools, use these legal alternatives:

• Plastic Spork or Bamboo Utensil: Avoids the struggle of eating terminal food with flimsy or non-existent plastic cutlery.
• Roll of Duct Tape (Flat Pack): Don't bring the whole roll. Wrap about 2 meters around a credit card. It can fix a torn bag, a peeling shoe sole, or a broken zipper.
• Carabiners: Two small, climbing-grade carabiners on your bag straps allow you to clip water bottles, hats, or neck pillows to your person, keeping your hands free.
• Emergency Cash: Hide $50/€50 (or equivalent) in a separate spot from your wallet, such as inside a phone case or a hidden pocket.

Critical Reminders

• The Liquid Rule: All gels, pastes, and liquids must be in containers of 100ml or less and fit into a single, transparent, quart-sized/1-liter resealable bag.
• No Sharps: While some regions allow small scissors, many international hubs will confiscate anything with a blade. Stick to nail clippers for your cutting needs.
• Weight Check: Aim for this kit to weigh no more than 1.5kg (3.3 lbs). Heavy carry-ons are increasingly being weighed at the gate by budget airlines.
