If you’re flying internationally for the first time – or just haven’t done it in a while—there’s much more to think about than just booking a seat and showing up. Border control, entry forms, baggage limits, and airport routines change once you leave domestic airspace.
You need a smooth plan that minimizes surprises. So, before you head off to the airport with your passport, we recommend you sort this out in advance.
Make Sure Your Passport Isn’t Too Close to Expiring
This one catches people off guard. Many countries won’t let you in if your passport expires in less than six months. Some even count from your arrival date, not departure. If your passport is due to expire within a year, renew it now. You won’t want to be told at check-in that you can’t board.
Check Visa Requirements for Every Country You’re Entering
Some countries still require a visa even if you pass through on a layover. You should double-check your destination and transit country on official embassy websites. Visa rules vary—Europe’s Schengen zone doesn’t ask for one if you’re from the U.S. or Canada, but Turkey, Egypt, or Australia might. And don’t assume visa-on-arrival applies to everyone.
Know Your Airline’s Baggage Rules
International flights often include checked baggage, but don’t take it for granted – low-cost carriers like Ryanair or Wizz Air charge extra for almost everything. Airlines also have different weight limits. If you carry gifts or bulky clothes, weigh your suitcase before leaving home. And if your carry-on is just over the size limit, it may end up in the hold.
Arrive Earlier Than You Would for a Domestic Flight
You’ll want to be at the airport at least three hours before takeoff for international departures. Between passport control, longer security lines, and sometimes filling out departure cards, time disappears quickly. Add extra buffer time if you’re traveling during peak hours or holiday seasons.
Have Printed Copies of Key Documents
Even in the digital age, paper still matters. You should carry a printed copy of your flight confirmation, hotel address, and travel insurance. If your phone dies or an official asks for proof, you’ll be glad you had a backup. Some immigration desks still ask for your accommodation details and a return ticket.
Research Arrival Airports Ahead of Time
If you land in a big hub like Heathrow, Charles de Gaulle, or Dubai, expect long lines and multiple checkpoints. Know which terminal you’re landing in, and how to get to the city center from there. You don’t want to arrive jetlagged, with no clue where to go. Apps like Rome2Rio or the airport’s website can help you plan the first leg after landing.
Don’t Skip Travel Insurance
Lost luggage. Delayed connections. Medical emergencies. When you’re far from home, minor problems get more prominent. Travel insurance isn’t expensive, and it can save you thousands. Many providers offer coverage for trip cancellations, medical bills, or stolen items. If you’re bringing expensive gear, check if electronics are included.
Know What You Can and Can’t Bring
International security screening is strict. Liquids over 100ml still need to go in a clear plastic bag, and some items, even snacks, are restricted in certain countries. For example, Australia has severe biosecurity rules. If you’re unsure about what’s allowed, check the customs website of the country you’re visiting. Better safe than having your favorite item confiscated.
Prepare for Different Currencies and Fees
Not every airport or taxi stand accepts credit cards. Have a small amount of local currency ready for your arrival. Also, let your bank know you’re traveling internationally. If they flag your card for suspicious activity, you might be locked out of funds at the worst time. Bring at least one backup card and avoid exchanging money at the airport unless necessary.
Understand Immigration Forms and Health Declarations
Some countries will ask for completed health forms or arrival cards before you reach the passport counter. These can be handed out on the plane or required online in advance. Check your airline’s website or your destination’s government site for entry requirements. A missing form can hold you up for hours.
