What You'll Learn

Domestic vs. international flights
While there isn't a one-size-fits-all answer to the question of how early you should get to the airport, the general rule of thumb is that you should arrive at least two hours before departure for domestic flights and three hours for international flights. However, this can vary depending on several factors, including the airport, the day of the week, and whether you are travelling with checked luggage.
For domestic flights, most airlines and airports recommend arriving at least two hours before departure. This allows enough time for checking luggage, going through security, and reaching the gate. Some sources suggest that 90 minutes is sufficient for domestic flights, especially if you are not checking luggage. The minimum check-in time for domestic flights is typically 30 to 45 minutes before departure, and you must be at the gate 15 minutes before scheduled departure.
For international flights, the check-in and security processes can be more time-consuming due to additional document checks and larger crowds. Therefore, it is generally recommended to arrive at the airport three hours before your scheduled departure time. Some international airports may have specific recommendations, such as Arturo Merino Benítez International Airport in Chile, which suggests arriving three to three and a half hours early during peak periods.
It is important to consider the specific airport's layout and your familiarity with it. Larger airports or those with longer distances between terminals may require additional time to navigate. Additionally, travelling during peak seasons, holidays, or busy travel times can significantly impact the foot traffic and wait times at airports, so it is advisable to allocate extra time during these periods.
When travelling with checked luggage, it is crucial to factor in the cutoff times for checking bags. For domestic flights, this is usually about 45 minutes before departure, while for international flights, it can be up to an hour. If you are travelling with children or require special assistance, it is recommended to arrive earlier to allow for additional paperwork or services.

Time of day and year
The time of day and year can be a significant factor in determining how early you should get to the airport. Flying during peak hours or busy days can lead to longer lines and wait times. Typically, weekdays, early mornings, and late evenings are less busy, while weekends, Mondays, and Fridays tend to be among the busiest times for air travel. Major holidays like Thanksgiving, Christmas, and the Fourth of July can also result in increased foot traffic and longer lines at airports. Therefore, it is advisable to allow for extra time during these periods.
Additionally, the airport's size and layout can impact your experience. Larger airports may have longer walks to the gate, while smaller airports may be quicker to navigate. Leisure-focused airports, such as Orlando, can take hours to get through, while some airports, like Ronald Reagan National Airport in Virginia, are designed for faster processing. Checking the airport map beforehand can help you estimate the time needed to reach your gate.
The day of the week and time of year can also influence the airport's busyness. While weekdays often have shorter lines, flying during peak travel periods or holidays can result in longer lines and unpredictable wait times, even for experienced travellers with fast-track privileges.
To make an informed decision, consider using real-time line data available through apps like MyTSA, which provides information for airports across the country. By checking the app, you can get an idea of the current wait times and plan your arrival accordingly.
Furthermore, the time of day can impact your experience at the airport. If you are looking to avoid larger crowds, consider flying in the middle of the day or later in the evening. These off-peak hours tend to have fewer people, making your journey through the airport smoother and faster.

Baggage check-in
Checking in early for your flight can provide peace of mind and give you extra time to navigate the airport. The time required for baggage check-in depends on various factors, including the airline, the destination, and the type of flight (domestic or international). Here are some guidelines and recommendations for baggage check-in:
Domestic Flights:
For domestic travel within the United States, it is recommended to arrive at the airport at least 2 hours before departure. The minimum recommended time to be at the airport is 45 minutes before departure, and some sources suggest 90 minutes to 2 hours for greater peace of mind. The baggage check-in cutoff time is typically 45 minutes before departure, and some airlines may have stricter cutoff times. Therefore, it is crucial to check your airline's specific baggage check-in policies.
International Flights:
For international flights, it is generally recommended to arrive at the airport three to four hours before departure. This allows sufficient time for checking in, navigating security, and completing any necessary passport checks, visa applications, or customs inspections. The check-in cutoff time for international flights is typically 60 minutes before departure.
Online and App Check-In:
Many airlines allow passengers to check in online or via their mobile apps starting 24 hours before departure. Some international airlines even offer online check-in 48 hours in advance. After checking in electronically, you can drop off your bags at the airport before your flight.
Early Bag Drop-Off:
Some airlines allow passengers to drop off their checked bags several hours before their flight. For example, United Airlines accepts baggage check-in up to 24 hours in advance, while Southwest Airlines accepts baggage as early as 4 hours before departure. However, it is important to note that some airlines may have restrictions on early bag drop-off, such as a 6-hour limit before scheduled departure. Always check with your airline to confirm their specific policies and recommendations.

Airport size
The answer to the question of how early is too early to go to the airport depends on several factors, including the airport's size and layout, your destination, and whether you require special assistance. Most airports have a cut-off time for checking in luggage, which is typically 45 minutes for domestic flights and up to an hour for international flights. Therefore, arriving at the airport a day early is not feasible, as you will not be able to check in or obtain a boarding pass until 24 hours before your flight.
While there is no legal limit to how early you can arrive at an airport, you may encounter restrictions on when you can go through security. Some airports may not allow passengers to enter the secured areas or go through security until the calendar day of the flight, especially if it is departing early in the morning. Additionally, some airports may have rules against staying overnight, and there may not be many amenities or shops open during late or early hours.
To ensure a smooth airport experience, it is generally recommended to arrive two hours before departure for domestic flights and three hours for international flights. However, this may vary depending on other factors such as the airport, luggage, and time of year. For example, flying during peak travel periods or holidays can result in longer lines and delays, so it is advisable to allocate extra time. Conversely, if you are travelling with only carry-on luggage and have priority privileges, you may be comfortable arriving at the airport closer to the departure time.
Ultimately, the decision of how early to arrive at the airport depends on your personal preferences and comfort level. While some individuals prefer to arrive well in advance, others opt for a last-minute dash to the gate. Considering the various factors and allowing for potential delays will help you plan your travel day accordingly.

However, there are several factors that can influence how early you should arrive at the airport, such as whether you are travelling with children, your luggage situation, the airport you are flying out of, and the day of the week.

- International Driver's Permit: If you plan to drive at your destination, look into obtaining an International Driver's Permit.
- Travel Advisories and Local Requirements: Review specific travel advisories and local requirements for your destination. This includes researching any COVID-19-related documents that may be necessary for entry.

- Emergency Contacts: Make sure to carry emergency contact information, including details of a trusted friend or relative who can be contacted in case of any issues.
- Copies of Documents: Make multiple copies of your travel documents and keep them separately from the originals. This will help in case your originals are lost or stolen.
