Best Airlines To Fly International 

Flying internationally can be complicated enough, even when you’ve already chosen your airline. But if you need help choosing the best international airline for your trip, the most important factor is your destination. Different airlines fly to different destinations and most carriers have specific regions where their routes and fares offer the best options for that part of the world. If you start by narrowing down your destination to a specific region, country, or city, then your best options will often make themselves clear, based on available routes and flight times. 

Best Airlines from U.S. to Europe

Choosing the best airlines from the U.S. to Europe depends on your definition of “best.” If you want an airline with more routes to European cities, choose American Airlines or Delta Air Lines.

International Travel Tips

Choosing an international airline is what you make it. Do you want luxury or economy? Lots of various destinations or a few spectacular ones? These choices and others will define which carrier you choose as your best international airline. 

The destinations you choose will largely guide your available options, so choose your routes carefully. Every continent, country, city, and neighborhood offers an opportunity to surround yourself in a new culture with the chance to meet new and fascinating people.

Because many international flights can  last 10 hours or more, arriving at your destination refreshed and in the mood to conduct business or to explore is important–and could make or break your entire journey. 

That’s why choosing the right airline for your international flight is critical. 

With that in mind, here are a few things you may want to know before you book your next trip to another country.

How Do I Get a Passport?

Although the details surrounding the passport process are different in every country, typically, it begins with gathering your official identification documents, such as a driver’s license and birth certificate. Next, find the website for the state department of the government where you’re a citizen. Search for information about applying for passports. Download a form and fill out the required information, including information from your identification documents. Copies of your identification documents will most likely be required, as well as a headshot photo cropped to specific dimensions. You will likely have to pay a fee for the passport. If you prefer, these websites will list office locations where you can bring your identification documents, photo and payment to apply in person. If you follow directions and all goes smoothly, it often takes several weeks to receive your passport. 

What To Look For When Choosing an International Airline

When it comes to choosing an international airline, everyone has different priorities. Your choice of airline may depend on a combination of infinite factors, including comfort, safety, services, amenities, seating, ticket fares, routes, times, and even what type of aircraft you want to fly on. Let’s take a quick look at some of these factors. 


International flights often require passengers to remain seated for 10 hours or more, which makes the distance between seats a very important metric–especially for passengers with long legs and wide behinds. The common measurements for this are width and seat pitch–the distance from seatback to seatback. Each airline determines seat configurations for its aircraft. SeatGuru.com has some of the best data on seat dimensions. If seat comfort is important to you, book your international flight accordingly.  


Flying on commercial airlines is proven to be among the safest modes of travel in the world, according to carefully monitored and easily available data. That’s largely due to regulatory oversight by aviation authorities in each country. 


Sometimes, if the food, drinks, and inflight entertainment are good enough, they can make a good international flight unforgettable. The best international airlines know this, and so they make a point of offering passengers delicious meals, refreshing beverages, and top-notch options for movies, TV, and games. Check out the food, drink, and entertainment fare listed on each airline’s website or app. 


Amenities on international flights can range from the bare basics (like free headphones), to semi-private, lie-flat seats with accouterments such as skincare products, eyeshades, blankets, and pillows, to the extreme–including a private suite and an onboard shower. Amenities are listed on each airline’s website. If amenities are important to you, then book your airline accordingly. 


Some air travelers consider an airline’s fleet when booking international flights. Every airline’s fleet offers a different mix of aircraft, each with various attributes pertaining to age, cabin size, engine noise, and seat configuration. Travelers who know, for example, that a specific international airline flies a new aircraft type on a particular route may wish to book that airline for their trip because they are familiar with the aircraft and want the specific attributes that type of jetliner offers.

Which airline is the cheapest to fly to Europe?

But in general, Norse Atlantic Airways offers some of the cheapest flights from New York City to London, as does Ryan Air. JetBlue Airways offers some of the cheapest flights from New York City to London as well as from Los Angeles to London. Wizz Air also has some of the cheapest fares from Los Angeles to London.

Is it safe to travel now?

Yes it is safe to travel now, although just like everything else in life, there are no guarantees. The keys to safe travel are knowing your personal limitations and doing your research about where you’re going. Then, based on your research, execute best practices for the countries you plan to visit. Is COVID-19 an issue in the country where you’re planning to travel? What about local security concerns such as terrorism or unrest? Find out by checking the U.S. State Department website, which regularly updates specific travel advisories for hundreds of countries around the world.

Is the Caribbean considered international travel?

It depends on where you’re coming from and where you’re going. For example, if you’re flying from the United States to a U.S. territory in the Caribbean such as Puerto Rico or the U.S. Virgin Islands, then no, the Caribbean would not be considered international travel. If you’re traveling from one country to another in the Caribbean, then yes, it would be considered international travel.
