10 Essential Tips for International Flights: Things You Should Know Before Flying

Taking an international flight can be exhilarating—it often marks the beginning of an exciting trip. But let’s be real: it can also feel overwhelming, especially if you’re unprepared. From navigating airport logistics to staying comfortable during a long-haul flight, these international flight tips will help you be fully prepared before you fly.

1. Familiarize Yourself with Airline Luggage Policies

One of the first things to check is your airline’s baggage rules. Every airline has specific requirements for the weight, size, and number of checked bags you’re allowed. Exceeding these limits could lead to hefty fees, so avoid surprises by planning ahead.

• Pro Tip: If your trip involves connecting flights with different airlines, double-check the baggage rules for each segment. Policies may be different, even on the same ticket.

2. Pack Essentials in Your Carry-On

When packing your carry-on bag, think about worst-case scenarios: What if your checked luggage is delayed or lost? Keep essential items like medications, a change of clothes, travel documents, contact lenses, eyeglasses and valuables with you.

• Follow the TSA’s 3-1-1 rule for liquids: containers must be 3.4 ounces (100ml) or smaller, placed in a single quart-sized bag.
• Bring a portable phone charger and headphones to stay connected and entertained.

3. Arrive at the Airport Early

International flights require more time for check-in, security, and customs. Arrive at the airport at least three hours before departure to avoid feeling rushed. This gives you enough time to check in, drop off your luggage, go through security, and find your gate.

• Morning flights: May have fewer delays and shorter lines.
• Evening flights: Potentially quieter airports but be prepared for delays.

4. Keep Your Travel Documents Handy

You’ll need to present your ID or passport multiple times at the airport—when checking in, passing through security, and sometimes again when boarding. To avoid fumbling through your bag or wallet, keep your identification easily accessible in a secure place, like a passport holder. This will save time and help the entire security process go more smoothly.

You’ll need your passport, visa (if applicable), and boarding pass multiple times at the airport—when checking in, passing through security, and sometimes again when boarding. Store them in an easy-to-access yet secure place like a travel wallet or a zippered compartment in your carry-on.

5. Dress for Comfort and Security Checks

Comfortable clothing is essential for long flights. Choose breathable, loose-fitting clothes and wear shoes that are easy to slip on and off for security checks. Layering is key as airplane cabins tend to get cold.

• Avoid excessive jewelry or accessories to breeze through security checkpoints.
• In addition to taking off your shoes, remember you’ll need to empty your pockets, remove your belt, jacket, and laptop from your bag.

6. Bring Your Own Travel Pillow and Blanket

While airlines often provide pillows and blankets on long-haul flights, they’re not always the coziest or cleanest. Invest in a high-quality, compact travel pillow and a lightweight blanket to stay comfortable.

• Pro Tip: Use a scarf or hoodie as a makeshift blanket or pillow in a pinch.

7. Stay Hydrated During the Flight

The dry air in airplane cabins can dehydrate you quickly, leading to fatigue and discomfort. Bring an empty, reusable water bottle through security and fill it up before boarding. Sip water regularly during the flight.

• Pack hydrating snacks like fresh fruit or cucumber slices.
• Limit caffeine and alcohol intake, as these can contribute to dehydration.

8. Plan for Jet Lag

Flying across multiple time zones can throw off your body’s internal clock, resulting in jet lag. Start adjusting to your destination’s schedule a few days before your trip by shifting your meal and sleep times.

• Use apps like Timeshifter to manage your sleep schedule.
• Bring an eye mask, earplugs, or noise-canceling headphones to get as much rest during the flight

9. Check-In Online and Track Your Flight

Save time at the airport by checking in online 24 to 48 hours before departure. You can also select your seat and download your boarding pass to your phone. Use apps like FlightAware to monitor your flight status in real-time.

• Pro Tip: Choose a seat near the wing for less turbulence or an aisle seat for easy access.

10. Prepare for the Unexpected

Sometimes, flights get delayed or canceled, or you might miss a connection. Stay calm and have a contingency plan. If your flight is delayed or canceled, most airlines will put you on the next available flight. Be sure to check your airline’s app or website for updates.

• Book flights with travel insurance to cover unexpected costs.
• Carry a list of local hotels and alternative transportation options in case of emergencies.

• Download Entertainment: Pre-load movies, podcasts, or eBooks on your phone or tablet to keep yourself entertained during the flight.
• Carry Cash: Some destinations or smaller airports may not accept credit cards everywhere. Have local currency on hand just incase.
