Traveling the world has never been easier than it is in the 21st century. Still, knowing your international airports can make your journey smoother and safer.
Almost every single country in the world has at least one international airport. In fact, out of the total of 159 official countries that exist, only five do not have an international airport. Those five countries are Andorra, Liechtenstein, Vatican City, Monaco, and San Marino.
Read on to learn more about international airports, including the countries that don’t have them and how many there are. I’ll also tell you which are the biggest and the best!

Which Countries Is International Airports In?
Almost every country in the world has at least one International airport. In fact, many have more than one. For example, the USA has about 150 of them, India has 34, and Germany has 16. Regardless of where you want to go, there’s an international airport nearby for you to fly into.
What Is an International Airport?
International airports are usually large airports that receive flights from other countries worldwide. This differs from domestic and local airports, which only allow travel within a single country, state, or region.
International airports are generally larger than other airports and employ customs and border control services that monitor and regulate the exchange of goods between countries.
If you fly out of your home country, you’ll want to be prepared for customs and border control!
What Are Airport Customs and Border Control?
When you fly into or out of any country, you must go through customs and immigration. Doing so requires that you have your travel documents and luggage checked by airport security or Border Control officers.
They’ll ask you a few simple questions about where you’re visiting and why, how long you’re staying, and where you’ll be staying.
If your documents are in order, and you’re allowed entry, you’ll need to declare any goods you’ve brought in your luggage, whether you got them from home or purchased them abroad. If your bags are checked, and you have restricted goods you didn’t declare, the airline officials may take the goods from you, and/or you may have to pay fines. For this reason, you must review customs regulations before you fly.
