You packed your bags, charged your devices, and downloaded the airline’s app. But some of the most important parts of travel preparation aren’t obvious — and skipping them can cause unexpected trouble.
Every adult flying out of a U.S. airport now needs a REAL ID or a valid passport to get through security. It’s a small change with big consequences for anyone caught off guard. And it’s hardly the only hidden hang-up for travelers.
These cumbersome details (that you’re likely unaware of) can derail your trip, delay your plans, or drain your wallet. Being aware of them ahead of time can be the difference between coming home with memories and coming home with regrets.
- Make sure your documents are valid
Expired travel documents are one of the easiest things to overlook — and one of the fastest ways a trip can fall apart.
A REAL ID — essentially a more secure driver’s license — is now required for domestic flights. For international trips, a passport is still necessary. Some countries require it to be valid for at least six months beyond your return date or have multiple blank pages. Others want to see proof of a hotel booking or a return flight before you’re allowed through immigration. Countries like Brazil, China, India, Russia, and many across Africa still require a full visa to be arranged in advance.
Most airlines don’t flag these details for you. Your documents may look fine, but if they don’t meet the rules at your destination, they won’t get you in.
- Choose a travel-friendly credit card
Using your credit card abroad can cost more than you expect.
Many U.S. cards charge a foreign transaction fee — usually 1% to 3% — every time you make a purchase in another currency. This includes online bookings made before the trip, like hotels or train tickets.
Some cards also aren’t accepted in certain countries. American Express and Discover, for example, don’t have wide coverage in parts of Europe, Asia, or Latin America. You may also run into issues if your card doesn’t support chip-and-PIN. And while ATMs might seem like a backup, they can add fees on top of what your bank already charges.
The best move is to carry a card with no foreign fees, make sure it’s widely accepted, and let your bank know you’re traveling. That step can help you avoid surprise charges.
- Determine how to stay connected
International roaming is one of the most expensive mistakes travelers make. U.S. carriers charge $10 to $12 per day for travel plans, and that can stack up fast.
A better option is an eSIM, a digital SIM card you can install on your phone before the trip. It connects you to local networks without swapping anything out. Most eSIM plans charge by the gigabyte or offer flat-rate regional packages, which makes it easier to stay on budget. Many travelers skip calling and texting entirely and stick with apps like WhatsApp and iMessage.
Americans spent about $23.7 billion on roaming-related charges in 2023. With less hassle and lower prices, eSIMs are becoming the go-to option for staying connected abroad.
