Discover how early you should really arrive at the airport

If you're gearing up for a trip and aren't a regular flyer, you might be asking yourself: “What time should I get to the airport?” Most airlines offer a general guideline that typically accommodates the average traveler's needs.

That said, various other elements come into play, such as airport procedures, baggage deadlines, seasonal factors, and the requirements of your travel companions. Depending on your situation, your airport arrival might need more or less time. Once you’ve downloaded the Dinogo mobile app and started planning the exciting aspects of your trip with Dinogo Trips, here’s how to figure out the best time to arrive at the airport for a hassle-free travel experience.

1. Ideal arrival time for domestic flights

In the U.S. and many other nations, most airlines advise that passengers arrive at the airport two hours prior to a domestic flight. This time frame covers everything from check-in and baggage handling to security checks and boarding cutoffs. However, during busy holiday seasons, it’s wise to allow some extra time for increased traffic and longer queues.

For the average traveler without special security clearances, some knowledge of the airport, and especially if you’re checking a bag, arriving at the airport two hours early is recommended. If you have access to expedited security options like TSA PreCheck or an airport reservation program, hold airline status, and are traveling with only carry-on luggage, you can typically reduce this time slightly.

The two-hour guideline for domestic flights refers to the time before departure. It already takes boarding cutoffs into consideration, so you don’t need to factor that in separately. However, if you're traveling with young children, in a group, or during peak times, you might want to add some extra time to that two-hour suggestion.

2. Recommended arrival time for international flights

For international travel, airlines generally recommend that you arrive at the airport three hours prior to your scheduled departure. This timeframe should cover all aspects of the airport experience, from checking your baggage to passing through passport control and security, ensuring timely boarding.

One key factor to consider when planning your arrival time for international flights is that the boarding process typically takes longer—usually between 45 minutes to an hour—due to the size of the aircraft. Make sure to factor in this extra time as you plan your activities at the airport.

Also, remember your international flight check-in time. For most airlines, it begins about 24 hours before departure, similar to domestic flights. However, some carriers, such as Dutch airline KLM, allow check-in for international flights up to 30 hours in advance.

3. When do flights begin boarding?

The timing of when planes begin boarding varies depending on whether you’re flying domestically or internationally. Most domestic flights start boarding between 30 and 45 minutes before departure. In contrast, international flights typically require more time due to larger aircraft and a higher number of passengers. A good rule of thumb is to board 45 minutes to an hour prior to departure for international flights.

Boarding times are usually printed on your boarding pass, and you can also find flights that are actively boarding displayed on airport monitors. If you're ever uncertain, feel free to ask a gate agent for assistance.

4. Tips to help you save time at the airport

While many factors in air travel may seem beyond your control—such as flight delays and lengthy lines—there are several strategies that savvy travelers can employ to save time at the airport. Here are some essential tips to streamline your experience.

What’s the travel time to the airport?

Before calculating how much time you need at the airport, it's crucial to know how long it will take you to get there. Overlooking accurate travel time can throw off your entire plan to arrive early, and in the worst-case scenario, you might miss your flight, complicating your trip. Whether you opt for a taxi, a ride-share service like Uber or Lyft, or public transportation, make sure to consider the travel duration.

How large is the airport?

If you're departing from a major hub, like New York's John F. Kennedy (JFK) or Los Angeles International (LAX), it’s wise to allow for extra time. The vastness of these airports means you could be standing in line with hundreds of other travelers. Even after you pass through check-in and security, it may take a while to reach your gate, as some terminals are so lengthy and crowded that walking from one end to the other can easily take 20 to 30 minutes.

Conversely, if you’re flying from a smaller or more remote airport, you can generally expect shorter lines. This can be particularly advantageous when traveling with young children or large groups. Regardless of airport size, it's always smart to locate your gate first before indulging in shopping or dining, so you know how long it will take to get back.

How crowded is the airport?

Certain times of the year are notably busier at most airports. If you're traveling during holidays, be prepared for longer lines at every stage of the process. The same goes for summer travel, as many families are on vacation during this season. This is a key factor that may necessitate more time than what airlines typically suggest, so be sure to account for the extra time during these periods.

Throughout the year, Monday mornings and Friday afternoons also experience higher levels of business travel compared to the rest of the week, but standard airline recommendations should generally accommodate this.

Are you taking an international flight?

International flights typically involve additional checks for documentation at check-in, extra screening and security measures at the gate, and, in some cases, pre-clearing customs and border control for your destination before departure. These factors are why airlines usually recommend arriving an extra hour earlier for international flights.

What are the baggage cutoff times?

If you don't have any bags to check, you can streamline your airport experience by checking in online. However, if you do need to drop off checked baggage, this becomes a vital factor in determining how early you should arrive at the airport. You'll need to ensure you reach the front of the line before the airline's baggage cutoff time. Having priority status can help, but don’t take any chances.

How long are the security lines?

Security lines are often the main source of delays at airports, which is why many travelers worry about how early to arrive. This is particularly important if you're departing from a large or notoriously busy airport, or if you’re traveling during holiday periods.

However, airline arrival estimates generally account for most of the security wait times, so you shouldn’t need to factor in extra time unless your airport is facing unusual delays. Many airports now provide apps that offer real-time estimates of security lines, considering the expected passenger volume for that day. Some even allow you to reserve a time slot in the security queue, which can save a considerable amount of time.

Do you have access to expedited security?

Programs such as TSA PreCheck and CLEAR provide entry to expedited screening lanes, which can significantly reduce wait times (though this isn't guaranteed). Some airlines extend these benefits to passengers with elite status or those flying in premium cabins like business or first class. However, these options are generally available to most travelers for a fee. Keep in mind that there's an application process, so planning ahead is necessary to take advantage of this time-saving option. Occasionally, CLEAR offers sign-up bonuses directly at the security line.

Are you considering doing any shopping at the airport?

Shopping at the airport is purely optional, so you can skip it if you're pressed for time. However, if you'd like to grab some snacks or a book for your flight or visit a duty-free shop, it's wise to budget an extra 15 minutes to account for potential long lines at vendor locations.

Don’t overlook the additional perks

Airplane restrooms are far from ideal: no one ever claims otherwise. So, be sure to allow time to use the restroom at the airport before your flight. Typically, you won’t have to walk far from the gate, but ensure you return before the boarding cutoff, usually at least 15 minutes before departure, though it can be earlier. If traveling with little ones, it’s wise to add a few extra minutes.
