Travel terms, plainly defined
40 essentials for booking smarter, crossing borders, and not getting fleeced at the card terminal.
- Shoulder season
- The 4–8 week buffer just before and after a destination's peak season. Crowds are 30–50% lower and prices 20–40% cheaper while weather is still mostly favourable.
- High season
- The period of year when a destination receives the most tourists, typically driving the highest prices and busiest sights. Often aligned with local school holidays and ideal weather.
- Low season
- The least-visited time of year. Significant savings and short lines, but expect closed attractions, reduced ferry/flight frequency, and weather risks (rain, heat, cold).
- Schengen 90/180
- The visa-free rule for the Schengen Area: a non-EU traveller may spend at most 90 days inside Schengen within any rolling 180-day window. Exits and re-entries do not reset the clock.
- e-Visa
- A travel authorisation applied for entirely online before departure. Issued as a PDF or digitally linked to your passport. Distinct from visa-on-arrival, which is granted at the border.
- Visa on arrival (VOA)
- A short-term visa stamped into your passport at the destination's port of entry. Requires bringing exact cash in USD, a passport photo, and a return ticket. Subject to rule changes without notice.
- ETIAS
- European Travel Information and Authorisation System. The EU's upcoming pre-screen for visa-exempt visitors entering Schengen. Approx. €7, valid 3 years.
- Dynamic currency conversion (DCC)
- When a foreign card terminal offers to bill you in your home currency rather than the local one. The merchant's bank sets the exchange rate plus a 3–7% markup; always decline and pay in local currency.
- Geo-arbitrage
- Earning income from a high-cost economy while living in a lower-cost one. Foundational to the digital nomad lifestyle. Watch for tax residency triggers (often 183 days/year in a country).
- Slow travel
- Staying weeks to months in one place rather than touring multiple cities. Reduces transit cost and emissions, deepens cultural immersion, and unlocks monthly accommodation discounts of 30–60%.
- OTA (Online Travel Agency)
- A reseller of flights, hotels, and packages — e.g. Booking.com, Expedia, Hotels.com, Agoda. Convenient for cross-vendor search; downsides include opaque change/cancel policies and a service layer between you and the supplier.
- Layover vs stopover
- A layover is a short connection (under 24 hours internationally / 4 hours domestic) on a single ticket. A stopover is a deliberate multi-day pause that some airlines (Icelandair, Turkish, Emirates) allow for free or low cost on long-haul routes.
- Gateway city
- The major international airport serving as the typical entry point to a region or country (e.g. Bangkok for Thailand, Cairo for Egypt, Lima for Peru). Often cheapest inbound and best onward connectivity.
- Hostel categories
- Dorm = shared room (4–16 beds). Mixed/female-only dorms vary. Private room = en-suite or shared bathroom. Pod hostels offer dorm prices with curtained semi-private bunks; common in Tokyo, Singapore, and modern Western European hostels.
- eSIM
- A digital SIM card installed via QR code or app, replacing the physical plastic SIM. Compatible iPhones, recent Pixels, and most Samsung flagships can run a local data eSIM (Airalo, Holafly, Saily) alongside your home plan with no swap required.
- Travel insurance excess
- The amount you pay before insurance kicks in on a claim — typically US $50–200 per incident. Lower excess = higher premium. For luggage and personal-electronics claims, check individual-item caps separately.
- Carry-on weight limit
- The kilo (or pound) cap your airline enforces on cabin baggage. Varies wildly: 7 kg on Asian budget carriers, 10 kg on European low-cost, 23 lb (10.4 kg) on most US legacies. Weight matters more than dimensions on most enforcement spot-checks.
- ESTA
- Electronic System for Travel Authorization. The US pre-screen for visa-exempt visitors entering the US under the Visa Waiver Program. US$21, valid 2 years, multiple entries up to 90 days each.
- eTA (Canada)
- Electronic Travel Authorization, Canada's equivalent of ESTA. CAD$7, valid 5 years, for visa-exempt air travellers only (not land/sea).
- NRT (Non-Resident Taxpayer)
- For US citizens, the rare status of living abroad and qualifying for the Foreign Earned Income Exclusion (~US$120k tax-free in 2026). Triggered by passing the Bona Fide Residence or Physical Presence test. Doesn't affect FATCA reporting obligations.
- 183-day rule
- Common global threshold for tax residency: spend 183+ days in a country in a tax year and you may owe income tax there. Specific countries have additional triggers (real estate, family, primary economic interest). The rule of thumb is "any 6 months, anywhere, talk to a cross-border accountant."
- Perpetual traveler
- A lifestyle where you deliberately split time across countries to avoid triggering tax residency anywhere. Requires sub-183-day stays per country, careful tracking, and usually a low-tax legal domicile. Distinct from "digital nomad" (working remotely without tax-planning intent).
- No-FX-fee card
- A debit or credit card that doesn't charge a foreign-transaction fee (typically 1-3% of each charge). Charges the card network's mid-market exchange rate plus 0.5-1%. US options: Chase Sapphire, Capital One Venture, Schwab Investor Checking. UK: Halifax Clarity. AU: 28 Degrees.
- Multi-currency account
- A bank-like account that holds balances in multiple currencies and converts on your command (not at point-of-sale). Wise and Revolut are the dominant options. Cheaper than card FX for large transfers; equivalent for everyday spending.
- Neobank
- A digital-only bank without physical branches, typically built on a partner bank's licence. Examples: Wise, Revolut, Monzo, Starling, Chime. Strong on multi-currency, FX, and mobile UX; weak on cash deposits, in-person services, and complex products.
- FAM trip
- A "familiarisation trip" funded by a destination tourism board, hotel chain, or PR firm, intended for travel writers and influencers. Industry norm to disclose; we don't accept undisclosed FAM trips, see our editorial policy.
- JESTA
- Japan Electronic System for Travel Authorization, the planned pre-screen for visa-exempt visitors entering Japan. Multiple rollout delays; check official sources within 30 days of travel as of 2026.
- TN visa
- A US work visa under USMCA (formerly NAFTA) for Canadian and Mexican citizens in specific professional occupations. Granted on entry, no prior consular interview required, renewable indefinitely in 3-year increments.
- Low-cost carrier (LCC)
- An airline business model with cheap base fares and a la carte fees for everything else (seat selection, bags, food, change/cancel). Examples: Ryanair, easyJet, AirAsia, VietJet, Spirit, Frontier. Cheapest per-mile when you pack light and don't need flexibility.
- Full-service carrier (FSC)
- A traditional airline with bundled fares (checked bag, seat selection, meals on long-haul). Singapore Airlines, ANA, JAL, Cathay Pacific are reference-grade examples. Worth 10-30% premium over LCC on long-haul, marginal on short-haul.
- Hub-and-spoke
- An airline route network where most flights connect through one or two megahubs. Why your "direct" flight from a mid-tier US city to a mid-tier European city often costs more than flying via Heathrow or Frankfurt.
- Boutique hotel
- A small, individually-designed property (~10-100 rooms), often locally owned, distinct from chain hotels. Best booked direct (the property captures the OTA commission as savings or perks for you).
- Pod hostel
- A hostel format where dormitory bunks are enclosed in capsule-style pods with curtains, lights, and outlets. Combines dorm pricing with semi-private comfort. Common in Tokyo, Singapore, Western European cities.
- Couchsurfing
- A hospitality network where travellers stay free in locals' homes. Largely dormant since 2020 paid-membership pivot; alternatives: BeWelcome, Trustroots, Warmshowers (for cyclists).
- Day-of trip insurance
- A travel-insurance policy purchased after you've already departed. Limited carriers support this (SafetyWing, World Nomads); traditional insurers usually require purchase before departure. Premiums are higher and pre-existing-condition coverage is excluded.
- Evacuation coverage
- The portion of travel insurance that pays for medical transport — ambulance, air ambulance, or medical-grade flight repatriation. Critical for remote-area travel or adventure sports. Recommended minimum: US$100,000.
- Lounge access
- Entry to airline or independent (Priority Pass) lounges, typically including food, drinks, Wi-Fi, and showers. Justifies its cost for trips with 3+ flights/year, long layovers, or work-while-traveling. Bundled with premium credit cards (Chase Sapphire Reserve, Amex Platinum).
- Cost-of-living index
- A normalised score (often versus NYC = 100) ranking destination affordability. Numbeo is the most-cited consumer source. Use as a relative comparison only — real spend depends on neighborhood, lifestyle, and currency at the moment of travel.
