35 Airport Mistakes To Avoid Making
From security checkpoint blunders to pre-flight planning errors, these common airport mistakes can add unnecessary stress.
1. Pre-Flight Catastrophes
- Having a passport with less than 6 months validity, resulting in denied boarding for international flights
- Being denied boarding because you failed to research and obtain required visas for your destination
- Booking flights with tight connections which are especially risky at large airports
- Forgetting important documents such as passport or boarding pass
- Not checking flight status before leaving for the airport which might be delayed by hours or even a day, or moved earlier
2. Baggage Blunders
- Overpacking and exceeding weight limits, resulting in unexpected charges
- Packing forbidden items in carry on bag, causing you to unpack in public to remove the items
- Forgetting to secure liquids in clear, quart-sized bags for security screening
- Not having a pen for international travel paperwork
- Paying for overpriced bottled water instead of bringing an empty reusable bottle to fill after security
3. Timing Troubles
- Not accounting for traffic, weather delays, or public transportation disruptions for the drive to the airport
- Underestimating check-in and security processing times
- Booking early morning flights without considering limited transportation options, resulting in expensive transfers
- Falling asleep during layovers without setting an alarm and missing your flight
4. Security Slip-Ups
- Wearing complicated shoes or boots that take time to remove

- Assuming restaurants and cafes will be open 24/7 during layovers
- Assuming shuttle buses between terminals will operate during late-night or early-morning hours
6. Tech Mishaps
- Not bringing adapters or chargers in carry-on, leaving you with dead devices during long waits or delays
- Paying for expensive airport WiFi when free alternatives exist in nearby cafes or outside airport lounges
- Using airport WiFi for sensitive transactions which creates a security risk
7. Money Matters
