Why Travel Has Its Own Language
Walk into the world of travel planning and you'll quickly encounter a flood of unfamiliar words: layover, open-jaw ticket, visa on arrival. These aren't just industry jargon — they describe concepts that directly affect your itinerary, costs, and entry rights. Understanding them before you start researching gives you a real advantage.
This glossary covers the terms you're most likely to encounter when booking flights, arranging accommodation, and preparing travel documents. Once you're comfortable with the vocabulary, see our first-trip abroad guide for a deeper look at the planning process itself.
| Domestic flight | A flight that departs and arrives within the same country. |
| International flight | A flight that crosses a national border, requiring passport and potentially visa documentation. |
| Direct flight | A flight with no change of plane, though it may stop briefly at an intermediate airport. |
| Nonstop flight | A flight that travels from origin to destination with zero stops. |
| Check-in deadline | The latest time you can check in for your flight, typically 30–60 minutes before departure for domestic, longer for international. |
| Carry-on baggage | A bag small enough to fit in the overhead bin or under the seat in front of you; size and weight limits vary by airline. |
Flight and Booking Terms
These terms come up the moment you start searching for flights.
Layover
A stop at an intermediate airport between your departure city and final destination. Layovers can last from under an hour to more than a day depending on the itinerary.
Open-jaw ticket
A flight itinerary where you fly into one city but depart from a different one. For example, flying into Paris and returning home from Rome. Useful for multi-city trips.
Codeshare flight
A flight operated by one airline but sold under another airline's code. You may book with one carrier but board a plane operated by a different one.
Fare class
A category that determines the price, flexibility, and benefits of a ticket — such as whether you can change or refund it. Economy, business, and first class each contain multiple fare classes.
Itinerary
A detailed plan of your trip including flight numbers, dates, times, accommodation addresses, and any pre-booked activities.
Hub airport
A major airport that serves as a central connecting point for an airline's route network. Many international flights route through hub airports.
Travel insurance
A policy that can cover unexpected costs such as trip cancellation, medical emergencies abroad, lost luggage, or travel delays. Coverage varies significantly by policy; always read the full terms.
Ground transportation
Any transport used on the ground at your destination — buses, trains, taxis, rental cars, or ride-share services — as opposed to air travel.
Understanding the difference between a layover and a connection matters when choosing routes. A layover simply means you stop at an intermediate airport before your final destination — sometimes for a few hours, sometimes overnight. A connection refers to the act of boarding a second (or third) flight as part of the same journey. If your layover is very short, you may hear the term tight connection, which signals a risk of missing your next flight if the first one is delayed.

Documents, Visas, and Entry Requirements
Entry requirements vary widely by destination and nationality. Always verify current rules directly with the relevant embassy, consulate, or official government travel advisory before booking — requirements can change without notice.
- Passport validity: Many countries require your passport to be valid for at least six months beyond your travel dates. Check this well in advance.
- Visa: Official permission to enter a foreign country. Can be obtained in advance at a consulate or, in some cases, on arrival at the destination.
- Visa on arrival (VOA): A visa issued at the port of entry rather than before departure. Not available at every destination, and eligibility depends on your nationality.
- Electronic Travel Authorization (eTA): A pre-travel electronic permit required by some countries (such as Canada) for nationals of visa-exempt countries travelling by air.
- Entry stamp: An official mark in your passport confirming you were admitted to a country on a specific date.
Always Verify Entry Requirements Officially
