Domestic vs. International Flight: What’s The Difference? [Inc. Tips and Advice]

Domestic vs. International Flight: What's The Difference? [Inc. Tips and Advice]You’ve got a trip planned that requires you to leave the country, and you’ve never traveled abroad. Naturally, you have some questions that need to be answered before you can even begin to plan your trip, like what is the difference between a domestic and an international flight? As a family, we’ve been on our share of flights. Some international and some domestic. We have put together a handy guide to help you address your concerns and a whole lot more.

A domestic flight is one that stays within the same country while an international flight is one that arrives in a different country. If you live in the US, then a domestic flight would be one between one US state to another, or even within the same state. If your landing destination is outside the borders of the USA, then you’re on an international flight.

There is a wealth of information on this topic, and we have collected it all right here for your easy reference! Keep reading for all the details, including our tips for a better flying experience.

Your trip begins with an airport… so let’s start this post there as well.

If you’re visiting a new country, different from the one where your flight originated, then your flight is going to land in an international airport. The airport where you land will ask to see your passport, and possibly a visitor’s visa. They will ask you a few questions about your trip before letting you enter into their country. It’s very rare but some people may be refused entry to a country at that point, and sent on a flight back home (or to another destination).

This is what it looks when you enter the US, arriving on an international flight –

This picture was taken in the summer of 2015, when we entered the US. We arrived on an international flight from Israel, with a connecting flight in Rome. That nice guy at the bottom of the escalators was welcoming Americans back home and directing everyone to the right lines for border control. There are always separate lines for returning citizens and visitors.

Domestic vs. International Airports

International airports allow you to travel all over the world, as opposed to domestic airports, which generally only allow flights within the same country. The key difference here is that international airports are set up for border control and customs inspections. With longer runways – to accommodate larger planes – and larger terminals, international airports are often also much more extensive than their domestic counterparts.

While it’s true that some domestic airports may have “international” in their title, these types of flights are often handled on an irregular (and sometimes very rare) basis and may not suit your schedule. Domestic airports are built in a manner conducive to more localized travel, and as such, they cannot accommodate consistent international flights.

With nearly 20,000 airports in the United States alone, you may feel overwhelmed with the sheer volume to choose from.

Entering an international airport

You may still need to use the services of one of those 20,000 if you choose to layover to a larger airport from a smaller, domestic one – and you may want to do this for many reasons – but you will mostly want to focus on international airports starting. You can then plan around the one you’ve chosen if need be.

Passenger Volume

You may also want to consider passenger volume to help in decreasing your wait time and any potential delays. An airport like Hartsfield-Jackson International in Atlanta, Georgia, for example, sees well over 100 million passengers every year. If this is an issue for you, look online to see what kind of traffic airports near you see daily.

If they report more passengers than you’re willing to deal with, it may be beneficial to connect to another airport to avoid the crowds. You can always start by traveling to a nearby, lower-volume domestic airport, and then fly over to connect to your international airport of choice.

Shopping at an International Airport

If you forgot to pack something – or you wish to stop and enjoy what they have to offer – all major airports include stores of many kinds, including gift shops, restaurants, and food courts. You will generally find WiFi services available, as well as offices for currency exchange.

Many international airports feature duty-free shops where luxury items and amenities can be purchased tax-free. By selling mostly to tourists who will be taking these items out of the country, many local and national taxes are waived.

Not only will you find the standard fare of shops and eateries, but some international airports also provide areas deemed secure for passengers to rest and sleep who may have become stranded or laid over. More often, however, you will find hotels on the premises to allow for comfort and privacy.

Airports are often massive (more on that below), and as such, you may find yourself in need of on-site transportation. Thankfully, you will often find services for just that, such as rail networks, curbside pickup, taxis, shuttle services, and buses.

If you need to leave your personal or rental car at the airport, many have parking garages for your convenience. This is highly beneficial if you don’t want to bother with an airport pickup or taxi service upon arriving home.

What Are Some International Airports?

Here are some major international airports in the USA.

Detroit Metropolitan Airport

The Detroit Metropolitan Airport, or DTW, is one of the major international airports in the United States. Located in Romulus, Michigan, the DTW covers a massive 4,850 acres, with four runways totaling nearly 11 miles.

It averages over 35 million passengers every year, offering flights to 30 international destinations with 39 of the United States covered, as well. Not only the DTW Michigan’s busiest airport, but it also has one of the largest airline hubs in the country.

Minneapolis-Saint Paul International Airport

The Minneapolis-Saint Paul International Airport, or MSP, serves both the public and military for international flights. The MSP is located in Hennepin County, Minnesota, juxtaposed within 10 miles of both downtown Minneapolis and St. Paul.

Covering 2,930 acres, it’s a little over half the size of the DTW, with approximately seven miles of total runway. Averaging nearly 38 million passengers annually, the MSP ranks fairly high in terms of busiest airports.

Las Vegas McCarran International Airport

The Las Vegas McCarran International Airport, or LAS, is another large international airport. Located in Paradise, Nevada, it covers 2,800 acres and has four runways that span over eight miles combined.

With nonstop flights to cities in Europe, Asia, and the United States, it serves almost 50 million passengers every year.

Dallas/Fort Worth International Airport

The fourth busiest airport in the world (aircraft movement) and 15th busiest in passenger traffic, the Dallas/Fort Worth International Airport, or DFW, is located on the Dallas and Tarrant county line in Texas.

Clocking in at over 17,000 acres, it is the second-largest airport in the United States, so large that it has its own post office, medical emergency, police, and fire rescue. It serves more passengers annually than any other entry listed here – nearly 70 million.

Orlando International Airport

Located just six miles from downtown Orlando, the Orlando International Airport, or MCO, is the busiest airport in Florida. Open for public use, the MCO serves approximately 47 million passengers annually.

It covers over 13,000 acres, making this airport one of the largest in the United States, with four runways totaling nearly 10 miles in length.

What Are Some Domestic Airports?

Here are some popular domestic airports in the USA.

Dallas Love Field

The Dallas Love Field (DAL) airport was once Dallas, Texas’ main airport of use until the massive Dallas/Fort Worth International Airport opened in 1974. Located just six miles from Dallas, it sports roughly three miles of runways while serving approximately 16 million passengers annually.

Savannah/Hilton Head International Airport

A commercial and military airport, the Savannah/Hilton Head International Airport (or SAV) is located in Savannah, Georgia. With two runways that total just over three miles, it serves approximately 3 million passengers annually, with that number increasing every year.

The Savannah Air National Guard is located at the airport, serving to transport its personnel, as well.

John Wayne Airport

Serving Orange County, California, as well as the Greater Los Angeles area, the John Wayne Airport (SNA) serves over 10 million passengers every year. Smaller than others listed here, its two runways equal around 1.5 miles in total length.

The SNA is just 14 miles from the Disneyland Resort, while the famous LAX is 35 miles away.

Manchester-Boston Regional Airport

The Manchester-Boston Regional Airport (MHT) is another public airport located 3 miles from Manchester, New Hampshire. Its two runways total just over three miles in length.

The MHT generally serves around 1.5 million passengers annually and is New England’s fifth-largest airport in terms of passenger volume.

Palm Beach International Airport

The Palm Beach International Airport, or PBI, is located in Palm Beach County, Florida and has three runways that total just over three miles. It serves approximately 6.5 million passengers every year, with limited international flights.

These include seasonal routes to Montreal, and Toronto, Canada, as well as year-round access to the Bahamas.

Do You Need a Passport to Book an International Flight?

Yes. Any time that you are traveling abroad, a passport is mandatory and required. You must also display your passport to enter the country to which you are traveling. Keep in mind that a passport cannot be used as a form of identification when making an international flight; a separate type must be given, such as a driver’s license or military ID.

Do They Serve Meals on International Flights?

That depends. The answer used to be “absolutely”, and meals are still featured in most transatlantic flights. However, during shorter international flights, for example from one European country to another, they often serve only snacks and beverages. On a low-cost flight, international or otherwise, you can purchase snacks and drinks but they’re not included in the price of your flight ticket.

The class in which you are traveling plays a significant role in the quality of your meals. We’ve only traveled in economy until now (and have no plans on changing that, unless someone offers us a free upgrade *wink*). This is what a hot meal looks like when it arrives –

Nothing to write home about, in terms of the culinary experience. However, I always say it’s a welcome distraction on a long flight. Handling everything on such a small space is challenging and in a way, sort of entertaining.

When meals are served, you usually get a choice of vegan, vegetarian, kosher, low-sodium and diabetic meals. These all have to be pre-ordered when you book your flight or during the online check-in phase. If you don’t tell them in advance, the airline won’t have a special meal ready for you. Kids under 12 usually have their own kid’s meals.

Do They Provide Blankets on International Flights?

In our experience, you do on transatlantic flights. Since airplanes are often rather chilly forms of transportation, it is generally standard fare to receive a blanket, as well as a pillow for use during the flight. A lot of the time, you may even keep your blanket, unless it is explicitly stated otherwise by your flight attendant.

As such, some airlines will reuse both blankets and pillows, with a fresh plastic pillowcase applied for every new passenger. If this is a sanitary concern for you, airlines often will allow you to bring your carry-on pillow, provided its size is within acceptable guidelines. A great example is the Trtl Pillow.  Click here to see it on Amazon.

Some airlines really pamper you on transatlantic flights. On our flight to New York with Azerbaijan Airlines, we each received a small blue bag that had earplugs, an eye mask, a small toothbrush and toothpaste and even a pair of blue socks!

Do You Get WiFi on International Flights?

While WiFi availability is growing rapidly among air travel, it isn’t available on all flights and with all carriers. You will first need to check with your airline to ensure that they offer it, and then find out if your flight path has it as well. You can do this easiest by looking at the coverage map on your potential airline’s website.

Not only will this service cost you, but it is also limited in its functionality. Currently, it is expressly prohibited to make voice or video calls on a cell phone (using WiFi or otherwise) while in flight. However, that may soon be a thing of the past, as the FCC is considering modifying this law to at least allow for WiFi calling.

What Is a Transatlantic Flight?

I’ve mentioned that several times by now. As its name implies, transatlantic flights travel across the Atlantic Ocean, connecting passengers to the Americas (North, Central, and South), as well as the Middle East, Africa, and Europe. Depending on weather conditions, transatlantic routes – called North Atlantic Tracks (NATs) – change daily to compensate for any issues that weather may cause for aircraft.

For passenger convenience, eastbound flights are usually in operation during the night, while ones westbound operate during the day. Approximately 2,500 aircraft make transatlantic flights daily.

Transatlantic Flight Times

As mentioned above, the night-time hours of an eastbound flight will generally make landfall between 6:00 AM to 9:00 AM UTC. Conversely, daytime westbound flights will usually make landfall between the hours of 12:00 PM to 3:00 PM UTC. It can certainly vary though, so carefully check your tickets.

Transatlantic flights are obnoxiously long too. We have one booked for March. On our way to the US, we’ll be passing 12+ hours traveling from Tel Aviv to New York. On the way back, it’s going to be an 8-hour long flight from NYC to London, followed by a 5-hour flight from London to Israel. Not much fun, but that’s international travel for you.

Should I Lock My Luggage When Flying Internationally?

For your safety, you may most certainly lock your checked luggage when flying to any destination, provided you use a TSA-approved lock. Keep in mind, however, that TSA agents carry master keys that will unlock all approved luggage locks if they feel your luggage requires extra screening. No worries on carry-on luggage, though, since it’ll be with you at all times.

Furthermore, when flying internationally, once you make landfall outside of the United States, not all agents abroad carry master keys. If they feel the need to look inside your luggage, you may run the risk of having your lock cut off for them to complete their inspection. A great example is this TSA approved lock from Master Lock.

Tips to Make Your Travel Easier

Here are a few quick tips that could help you when traveling internationally.

1. Passports and visas

Lastly, and this is a big one, find out ahead of time if the country in which you are traveling has any entrance and exit fees. That’s right; some won’t allow you to do either without paying a fee. If that is the case, make doubly sure that you have cash set aside for such a situation, or an international credit card open for international transactions.

2. Make copies of your passport

Take clear photos of your passport’s main page. Keep them accessible on the cloud and also carry a printed copy with you. Leaving a copy with someone back home is always a good idea too (a digital copy should be enough).

3. Carry some local money (and/or a credit card)

Talk to your credit card company to make sure your card will work overseas while traveling. If traveling to Europe, you may need to upgrade to a card with the new chip technology. We usually prefer to carry some cash for the first days on us, just in case.

4. Vaccinations

You don’t want to go through all the steps of planning for a trip only to find out at the last minute that you don’t have proper vaccinations. Check with your doctor well in advance to ensure that you’re up-to-date.

Most western countries don’t require any vaccinations. It’s always good to be up to date on your tetanus and whooping cough shots though. With recent outbreaks of measles rampant around the world, make sure you’ve had two shots of that sometime in your life (people who are older than 40 were often only vaccinated with one dose and should add another). It’s always better to prevent hepatitis too, so we made sure we’re all fully covered for Hep A and Hep B. The former is especially an issue when traveling because it’s passed in food and water.

Last but not least, if you’re traveling in fall or winter, get that flu shot!

5. Carry your valuables and medications on you

Don’t send your medications in your suitcase. Have at least a week’s supply in the bag that you’re carrying with you. The same goes for any valuables. Luggage can and does get lost. We also carry a change of underwear and one set of clothes for each person in the trolley that we take on board the plane. Meds and everything that is absolutely necessary for the flight itself stays in our handbags or even pockets. Some airlines may ask you to send your trollies too, right at the gate, so it’s best to be prepared.

6. Get some food and an empty bottle for the flight

Even if food is served, I like to have some snacks with us. Just in case the boys don’t like the food served, or that someone gets hungry in between meals. Energy bars are a good alternative, as they’re small and filling. You can’t carry a full bottle of water through security, so we buy one after passing the check and while waiting at the gate. During the flight, I get up and fill it up to keep hydrated.

7. Get up often during the flight

It’s very tempting to just cocoon up during a long flight, avoiding drinking and bathroom visits. That’s a huge mistake, especially for adult travelers. It’s very important to stay hydrated and move around to prevent blood clots from forming.

8. Lip balm and hand cream can come in handy

Airplane air is dry, so if you’re prone to chapped lips and dry skin, get some with you in advance. Find small travel-size products. Any large tubes (larger than 100CC) will be taken away from you during the security checks.

Final words

Flying can be a fun experience, though the longer it gets, the more tedious it tends to get. Still, you can’t do without it if you want to travel abroad. I hope you found this guide helpful.
