10 Things to Check Before Your First International Trip
There's something exciting about booking your first international trip.
One minute, you're looking at flights and imagining yourself walking through a city you've only seen in pictures.
The next, you're wondering whether your passport is valid, how you're supposed to get from the airport to your hotel, and whether your phone will even work when you land.
I remember that feeling.
Before my first international trip to Italy, I spent years wondering whether traveling overseas with type 1 diabetes was something I could realistically manage.
Eventually, I booked the flight.
And while that trip came with its share of surprises, it also taught me something important.
You don't have to know everything about international travel before you go. But knowing what to check beforehand makes a big difference.
Here are ten things I'd recommend reviewing before your first trip abroad.
Checking your passport and travel documents is one of the first steps when preparing for an international trip.
Check Your Passport Before Anything Else
Your passport is one of the first things to look at when planning international travel.
And I'm not just talking about whether you have one.
Check its expiration date, its condition, and the requirements of every country you're visiting.
Some destinations require your passport to remain valid for several months beyond your planned departure or return date.
Others have different rules.
Don't assume that a passport is acceptable simply because it hasn't expired yet.
The U.S. Department of State's international travel checklist is a useful starting point.
I'd also keep a secure digital copy of my passport and a separate backup of important travel documents.
Those copies won't replace the original for travel, but they may help if something gets lost.
Research Entry Requirements
A passport doesn't automatically mean you can enter every country.
Depending on your nationality and destination, you might need a visa, electronic travel authorization, proof of onward travel, or other documentation.
Requirements can also differ depending on how long you're staying and why you're visiting.
And if you're connecting through another country, don't forget to check whether any transit requirements apply.
I'd always confirm the rules using official government sources rather than relying entirely on a travel blog or a social media post.
Entry rules can change, and getting them wrong can create problems before your trip even begins.
Understand Your Money Options
Traveling somewhere with a different currency can make even ordinary purchases feel unfamiliar.
How much is that train ticket?
Is the restaurant expensive, or does the price just look different?
Should you exchange cash before leaving?
I like having a basic understanding of the local currency before arriving.
Check whether your credit or debit card charges foreign transaction fees, find out how you'll access cash, and consider carrying a small backup payment option.
If a payment terminal offers to convert a purchase into U.S. dollars, compare that option with paying in the local currency. The offered conversion rate may be less favorable than your card's rate.
You can also use the currency converter on Glucose Getaways to get a general idea of prices before your trip.
Just remember that exchange rates fluctuate, and your bank or card provider may apply its own rates or fees.
Figure Out How Your Phone Will Work
Your phone can become one of your most useful travel tools.
I use mine for navigation, train information, hotel confirmations, translation, and keeping track of reservations.
But international phone service isn't something I'd leave to chance.
Before leaving, check whether your existing mobile plan includes service in your destination.
If it doesn't, compare international roaming, a local SIM card, and an eSIM.
Make sure your phone supports the option you choose, and check whether it's carrier-locked.
I'd also download offline maps and save important addresses somewhere accessible without an internet connection.
You don't want to arrive in an unfamiliar city and discover that your entire transportation plan depends on a connection you don't have.
Plan Your Airport Arrival and Transportation
Booking a flight and hotel is one thing.
Figuring out how to get between them is another.
Before departure, I'd look up the airport's transportation options and determine which one makes the most sense for my arrival time, luggage, and budget.
That might be a train, airport bus, taxi, rideshare, or prearranged transfer.
I'd also check how tickets are purchased, where the transportation departs, and whether the service runs late at night.
This is one of those little planning steps that can save a surprising amount of frustration.
On my first international trip, a delayed flight disrupted my plans and I missed the train I'd expected to take after arriving in Rome.
I eventually figured things out, but it was a reminder that transportation plans need a little flexibility.

Understand Your Travel Insurance
Travel insurance isn't always the most exciting part of planning a vacation.
But it's something I'd take seriously, particularly for international travel.
There are different types of coverage, including trip cancellation, trip interruption, emergency medical expenses, and medical evacuation.
And they're not interchangeable.
A policy that reimburses a canceled hotel reservation doesn't necessarily provide the medical coverage you might need overseas.
The U.S. Department of State recommends considering travel medical insurance and medical evacuation coverage when traveling abroad.
I'd read the actual policy terms, not just the headline benefits.
Pay particular attention to exclusions, preexisting medical conditions, emergency definitions, coverage limits, and any requirements to contact the insurer before receiving treatment.
If you have diabetes or another chronic condition, it's especially important to understand how the policy treats unexpected emergencies related to that condition.
Never assume a condition is covered simply because a policy advertises emergency medical benefits.
Check Your Medication and Health Needs
International travel can change your normal routine.
Different time zones, unfamiliar meals, more walking, long transportation days, and unexpected delays can all affect how you feel.
For travelers with diabetes, these changes can also affect glucose management.
Before a trip, I think it's important to review medication storage requirements, carry-on supplies, prescription documentation, and backup plans.
I travel with type 1 diabetes, so insulin, my insulin pump, glucose monitoring equipment, and backup supplies are an important part of my preparations.
But the exact supplies someone needs will depend on their own medical situation.
The CDC's travel guidance for people with diabetes recommends planning ahead for medications, supplies, changes in activity, and different time zones.
If medication timing or treatment adjustments may be needed, those are conversations to have with your healthcare professional before leaving.
I'd also research whether my medications are permitted in the destination country and how I would obtain medical help if necessary.
Research the Destination Beyond the Attractions
It's easy to spend hours researching famous landmarks and restaurants.
But I'd also spend some time learning how the destination actually works.
What language is spoken?
How does public transportation operate?
Are businesses commonly closed on certain days?
Do restaurants expect reservations?
Are there local customs or etiquette expectations worth understanding?
You don't need to become an expert in the destination's culture before arriving.
But learning a few basics can make your experience smoother and help you be a more respectful visitor.
I also like knowing a little about the neighborhoods I'll be exploring rather than focusing exclusively on the most famous attractions.
Sometimes the ordinary moments between the major sights become the parts of a trip you remember most.
Pack for the Trip You're Actually Taking
One of the easiest ways to overpack is trying to prepare for every imaginable situation.
I'd start with the trip itself.
What's the weather likely to be?
Will I be changing hotels?
Will I be carrying luggage on trains?
How much walking am I expecting?
A two-week trip through several European cities might require a different packing strategy than a week at one resort.
I'd also check airline baggage rules, especially when multiple airlines are involved.
The Airline Bag Size Checker on Glucose Getaways can help with initial planning, but always verify the current allowance with your airline.
My goal isn't to pack as little as humanly possible.
It's to bring what I'll actually use without making the trip harder than it needs to be.
And essential medication and diabetes supplies aren't the things I'd sacrifice to save a little suitcase space.
Have a Plan for When Something Goes Wrong
I think this is one of the most overlooked parts of planning an international trip.
People spend so much time figuring out what they want to do that they sometimes forget to consider what happens if the plan changes.
What if your flight is delayed?
What if your luggage doesn't arrive?
What if you lose your wallet?
What if you need medical care?
You don't need a detailed plan for every possible emergency.
But I'd want to know how to contact my accommodation, reach my bank, access emergency funds, and find appropriate medical assistance.
For U.S. travelers, the State Department's Smart Traveler Enrollment Program is also worth considering. It provides destination-related alerts and can help U.S. embassies or consulates contact travelers during emergencies.
I also recommend sharing a basic itinerary and emergency contact information with someone you trust.
Preparation doesn't eliminate uncertainty.
It just makes the unexpected a little easier to handle.
Your First International Trip Doesn't Have to Be Perfect
Here's something I wish I'd understood before my first trip overseas.
You're probably going to make a mistake somewhere.
You might get confused at a train station.
You might take a wrong turn.
You might discover that the restaurant you wanted to visit is closed.
Or you might find yourself dealing with a delayed flight and a transportation plan that no longer works.
That doesn't mean the trip is ruined.
Some of my most memorable travel experiences have come from moments that didn't go according to plan.
Travel has taught me to prepare carefully, but also to be flexible enough to enjoy what's happening around me.
And if you've been putting off your first international trip because you're worried about everything that could go wrong, I understand that feeling.
I spent years thinking about the obstacles before I finally booked my first flight abroad.
I'm glad I eventually did.
“Prepare. Ask questions. Have a plan. Bring the backups. Then go see what’s out there.”
