Top 7 Baggage Mistakes Travelers Make in 2025
- Not checking your ticket’s baggage allowance Many “Basic” or “Light” fares include zero checked bags — a nasty surprise at check-in.
- Ignoring the 100ml liquid rule All liquids, gels, and aerosols must be in containers ≤100ml (3.4oz), placed in a single 1-liter clear bag.
- Putting power banks in checked luggage Lithium batteries MUST be in carry-on. Max 100Wh without approval, 100-160Wh (≈20,000-32,000mAh) needs airline approval (max 2 pieces).
- Packing valuables or medication in checked bags Cash, electronics, cameras, and medicine should always stay with you.
- Buying extra baggage at the airport Online pre-purchase can save 40-200% compared to airport rates.
- No name tags or photos of luggage Lost luggage recovery is nearly impossible without clear identification and photos.
- Assuming baggage transfers automatically during connections In the US, Canada, and some countries, you must collect and re-check bags during transit.
Pro Tips to Avoid Fees & Travel Like a Pro
- Pre-book extra baggage online — cheapest up to 4 hours before departure
- Use the rolling method for clothes + compression bags only for bulky items
- Replace liquids with solids (solid shampoo, toothpaste tablets, deodorant sticks)
- Always carry a change of clothes and medication in your carry-on
- Weigh your bag at home with a digital luggage scale
- Use AirTag/SmartTag for real-time tracking
- Take photos of your packed suitcase (inside & out) before leaving home
What to Do If Your Luggage Is Lost or Delayed
- Go immediately to the airline’s baggage service desk and file a Property Irregularity Report (PIR)
- Keep all receipts for essential purchases (clothes, toiletries) — most travel insurance reimburses up to US$500-3,000
- Follow up online using your PIR reference number
Final Advice Check your airline’s official website 48-72 hours before departure — rules change frequently. A few minutes of preparation can save you hundreds of dollars and hours of stress.
Safe travels and happy packing!
