10 Things Even Frequent Travelers Forget to Do Before Leaving for a Trip

While you may have booked your flights and packed your bags, there’s still so much more to do before leaving for a trip. In fact, even seasoned travelers can miss small but essential pre-trip details, focusing on packing and logistics while letting other essential tasks slip through the cracks. These easy-to-overlook steps often don’t become an issue until it is too late to fix them. 

From digital prep and document checks to finances, medication rules, and home setup, travel experts say these are the things people forget most often—and the ones that tend to matter more than expected.

Verify Entry Requirements

This was the one step every expert we spoke to called out first—and the one most likely to derail a trip before it even begins. Entry rules change frequently, and checking the most up-to-date requirements close to departure—even for familiar destinations—can help travelers avoid unexpected border issues, saysFTLO Travel founder and chief executive officer Tara Cappel.

Passport rules can trip up even seasoned travelers. Validity requirements, blank-page rules, transit-country regulations, and new electronic travel authorizations are easy to miss, especially since many travelers assume that an unexpired passport is enough. According to Fora co-founder and Travel + Leisure A-List advisor Henley Vazquez, “Many countries require at least six months of validity beyond the end of your travels or a certain number of blank pages.” It’s also worth noting that requirements can change based on where you are coming from, meaning even a short layover can cause problems if you are not paying close attention.

“Garden” Your Reservations

Jimmy Yoon, director of client services atPoint.me, says one of the most common missteps is not “gardening” reservations—his term for periodically checking bookings between purchase and departure for better rates, availability, or schedule changes. Per the pro, revisiting reservations can help travelers avoid surprise schedule changes, and, in the case of refundable bookings like points reservations, occasionally secure a better seat or a lower rate.

Take Photos of Key Documents

Before traveling, snap photos of your passport, credit cards, and any required visas or authorizations. Then, be sure to save them in a secure, easy-to-access location, such as a cloud account or a password-protected notes app. That way, you can easily access them if your wallet or physical documents are lost, stolen, or destroyed.

Check Luggage Rules—Especially for Basic Fares

Airlines change carry-on rules more often than most travelers realize, and the updates are not always easy to spot, especially on basic economy fares. Similarly, size and weight limits vary by carrier. For the most up-to-date information, refer to your airline’s baggage policy (available online) so you’re not forced to check a bag or, worse, pay surprise fees.

Set Up Your Phone Before You Leave

International cell service is something travelers don’t think about until they don’t have it. Jordan Rozum, director of product development at Point.me, recommends setting up an eSIM before departure so you can stay connected as soon as you land. Alternatively, depending on your cell phone plan and/or carrier, you may also be able to purchase international data packages in advance to avoid surprise bills.

Offline access is equally important, especially for navigation, which is why Rozum suggests downloading an offline map of your destination in Google Maps. However, he also notes that some places require alternatives. “In South Korea, for example, you will want to use Naver Maps instead,” and of course, you’ll want to download it in advance. 

Make Sure You Can Pay Everywhere

Payment prep is another step travelers often forget. “Apple Pay is much more widely used outside the U.S. than people realize,” says Cappel. That said, even in places where Apple Pay and credit cards are accepted, having some cash on hand is still a good idea. If you are traveling internationally, ordering the local currency through your bank before you leave usually gets you a better rate than airport kiosks, which tend to charge the most. Plus, you can hit the ground running, without scurrying to an ATM after a long-haul flight.

Let Your Bank Know You’re Traveling

Another easy but often overlooked step is notifying your bank that you will be traveling, especially if you’re traveling internationally. Even with improved fraud detection, international charges, especially across multiple countries, can trigger card freezes, which I’ve unfortunately learned the hard way. Fortunately, a quick heads-up can help prevent a card from being declined. 

Check Medication Rules

You may not think twice about packing medications for your trip, but many travelers forget to check whether those medications are permitted or restricted at their destination. Some countries ban or tightly regulate standard prescription and non-prescription drugs, including select painkillers, sleep aids, and cold, ADHD, and anxiety medications. Arriving with a banned medication, even if it was legally prescribed to you, can lead to confiscation, fines, or worse. To avoid any headaches, it’s always recommended to keep prescriptions in their original containers, and, to be extra safe, bring a doctor’s note. 

Set Your Home Up for Your Absence

While these tasks are by no means glamorous, pausing mail, tossing trash and perishables, and setting lights or timers can make returning home feel easy instead of chaotic. It also helps to adjust the thermostat so you are not heating or cooling an empty house, check that appliances like the stove or iron are off, and let a trusted neighbor or friend know you will be away in case something comes up.

A Five-minute Check Before Walking Out the Door

If travelers have only a few minutes before heading out, experts recommend focusing on the essentials. “I literally stand at my front door right before I leave and make sure I can see my passport, phone, and credit card in my bag,” says Cappel. “There have been more times than I would like to admit when I have gotten into an Uber and had to turn back!”
