The first day of a trip is the one most likely to go sideways. You're tired. You're possibly jet-lagged. You're making decisions in an unfamiliar environment with systems you don't fully understand yet. Bad choices made in the first few hours (the wrong currency exchange, the wrong sleep strategy, the wrong transportation call) have a way of setting the tone for everything that follows.
Before You Clear Customs: The Priority Order
Download or activate your data plan before you land. If you're using a local SIM or eSIM (see our connectivity guide for the full comparison), activate it on the plane or during taxi to the gate. You want maps and translation tools working before you need them, not after you're already lost.
Clear immigration with your documents ready. Passport open to the photo page. Arrival card filled out if your destination requires one. Most long-haul international destinations still do, and not having a pen at the immigration queue is a specific misery. Know the address of your first night's accommodation. Immigration officers may ask this, and fumbling through your phone for the information needed holds up the line and occasionally leads to additional scrutiny.
Collect checked bags before currency. Self-evident but worth stating: don't leave the baggage area to change money and then discover your bag arrived damaged or is missing. Bags first, everything else second.
Getting Local Currency Without Getting Robbed by the Exchange Rate
Airport currency exchange kiosks are everywhere at international airports and priced to exploit exhausted travelers. The spreads (the difference between what they buy currency for and what they sell it at) are often 10–15% above market rate. On $500, that's $50–$75 gone immediately. They also tend to be staffed by extremely cheerful people, which somehow makes it worse.
The better options, in order of preference:
Use a local ATM inside the airport, past security. ATM machines connected to local bank networks typically offer the interbank exchange rate with a flat fee, usually $2–$5. Your home bank may charge a foreign transaction fee on top of that (typically 1–3%). Combined, you're still well below the exchange kiosk rate on any meaningful withdrawal.
Use the ATM in the secured arrivals area, not in the departure halls or before passport control. Scammed or skimmed ATMs cluster in higher-traffic areas with less oversight. Machines affiliated with recognizable local banks are safer than standalone ATMs in airports.
Decline "Dynamic Currency Conversion" (DCC) at every opportunity. When an ATM or card terminal asks if you'd like to pay in your home currency rather than the local one, say no. DCC locks in an unfavorable rate set by the terminal operator, not your bank. Always pay in local currency and let your bank handle the conversion.
Bring a no-foreign-transaction-fee card. Charles Schwab Bank, Chase Sapphire, and Capital One Venture cards charge no foreign transaction fees and often reimburse ATM fees globally. If you're traveling internationally more than once a year, having one of these in your wallet costs nothing and saves consistently.
How much cash to get: Enough for the first 24 hours. Transportation from the airport, a meal, incidentals. Most cities are card-friendly and ATMs are accessible throughout; you don't need to carry a week's worth of cash out of the gate. Markets, small guesthouses, and rural destinations are exceptions. Pull more when connectivity and ATM access will be limited.
Leaving the Airport Without Paying Tourism Tax
Airport transportation is almost universally overpriced when you use the first option presented to you. The savvy traveler’s preferred hierarchy:
Rail or metro is the fastest and cheapest option at most major international airports. Heathrow to central London on the Elizabeth line: £12.50. Tokyo's Narita Express to Shinjuku: ¥4,070. These connections exist because airports built them; use them.
Pre-booked rideshare or taxi is the next tier. Book through the local equivalent (Grab in Southeast Asia, Bolt in Europe and parts of Asia, standard Uber where it operates) rather than accepting an airport taxi tout. Surge pricing can still bite, but it's almost always cheaper than the official airport taxi queue with its flat rates designed around business travelers expensing the ride.
Official airport taxis are the backstop. Legitimate, metered (usually), and more expensive than alternatives. When the rail doesn't run, when you have heavy bags, when it's late and you're done making decisions.
Avoid: Anyone approaching you in the arrivals hall offering a ride. In most international airports, unsolicited offers from non-uniformed strangers are either scams or significantly overpriced unmetered rides. Decline, walk to the official taxi or rideshare zones, and sort it from there.
The First Meal Decision
You're going to be hungry and slightly disoriented. The airport restaurant by the arrivals exit is expensive and mediocre in every country, a universal law as reliable as gravity. Walk five minutes further and it gets better; take the metro one stop and it gets significantly better. If your energy allows, resist the first option. If it doesn't, eat the overpriced airport sandwich and move on. It's one meal.
Check-In and the Orientation Window
Hotel or rental check-in is your first real base of operations. Use the first thirty minutes well.
Ask the front desk or host one useful question: what neighborhood are you in, and what's the practical thing to know about it? This is better than downloading a guide. You'll get current, specific information from someone who knows the area. Is there a good local market nearby? A transit card you should get? A neighborhood to navigate differently at night?
Walk the immediate block before you settle in. Figure out where the nearest pharmacy, ATM, and convenience store are. This costs ten minutes and pays dividends for the rest of the stay.
Beating Jet Lag: What Actually Works
The advice here depends on which direction you're traveling. East-west and west-east jet lag work differently and respond to different interventions.
The core principle applies to both: your circadian rhythm is driven by light exposure and when you sleep. You can accelerate adaptation by aggressively aligning with local time on arrival, rather than letting your body drift.
Traveling east (U.S. to Europe, for example) is harder for most people. You're compressing time. Get bright light exposure in the morning local time. Sunlight, not a lamp. Avoid napping after 3 p.m. local time. Take melatonin (0.5–1 mg, not the 10 mg dose sold in U.S. pharmacies) ninety minutes before your target local bedtime for the first two to three nights.
Traveling west (U.S. to Asia, Europe to the U.S.) is generally easier. You're extending the day. Get light exposure in the afternoon and evening local time. Don't sleep until local nighttime, even if you're exhausted at 4 p.m.
Melatonin dosing: most Americans take far too much. The therapeutic dose for circadian adjustment is 0.5–1 mg, not 5–10 mg. Higher doses don't accelerate adaptation; they cause grogginess and can disrupt sleep quality. The 10 mg gummy you bought at CVS is ten times what you need.
Caffeine: use it strategically the first two days. Caffeine taken in the first half of the local day supports wakefulness without compounding insomnia the first night. Avoid it after 2 p.m. local time for the first few days.
The one thing that genuinely doesn't help: trying to "sleep off" jet lag with long midday naps. You'll feel better for an hour and significantly worse the next two nights.
The First Night Decision
If you arrive exhausted in the morning local time, stay awake until local evening, at minimum 9 p.m. A short nap of ninety minutes or less (one full sleep cycle) in the early afternoon is acceptable and won't derail adaptation. Anything longer delays recovery by a full day.
Outdoor activity in natural light is the highest-leverage thing you can do on arrival day. A two-hour walk in the afternoon sun outperforms any supplement or sleep hack. It also happens to be a good way to see where you are.
The goal for day one is simple: make it to 9 p.m. local time without collapsing. Day two is almost always better.
