Have you ever wondered how long it takes for a plane to complete a flight? With over 100,000 flights taking off each day, the answer may surprise you! If you’re short on time, here’s a quick answer to your question: On average, it takes around 2.5 to 6 hours for a domestic flight in the US and 5 to 14 hours for an international flight.

In this comprehensive guide, we will cover everything you need to know about flight times and what factors affect them.

Average Flight Times

Domestic Flights

On average, domestic flights in the United States take around 2-3 hours. However, this can vary depending on the distance between the departure and arrival airports. Shorter flights, such as those between neighboring states, can take as little as 1 hour, while longer cross-country flights can take up to 6 hours or more.

It’s important to note that these times are just estimates and can be influenced by various factors.

International Flights

When it comes to international flights, the duration can vary significantly depending on the distance between the departure and destination countries. For example, a flight from New York to London usually takes around 7-8 hours, while a flight from New York to Sydney can take approximately 20 hours or more.

These times are based on non-stop flights, and layovers can add additional time to the overall journey.

Pro Tip: If you want to get an idea of the average flight times for specific routes, websites like Flight Durations can provide you with detailed information. They offer estimated flight times, including stopovers, for various destinations around the world.

What Affects Flight Times?

Several factors can affect the duration of a flight. One of the main factors is the speed of the aircraft. Different types of planes have varying speeds, which can impact the overall travel time. Weather conditions also play a significant role.

Strong headwinds can slow down a plane, while tailwinds can speed up the journey. Air traffic congestion and the availability of air routes can also affect flight times, especially during peak travel seasons.

Fun Fact: The fastest commercial flight on record was a British Airways flight from New York to London, which completed the journey in just 4 hours and 56 minutes, thanks to an exceptionally strong tailwind.

It’s worth noting that flight times are subject to change and are influenced by multiple variables. Airlines strive to provide the most efficient and timely service, but unforeseen circumstances can lead to delays or deviations in flight plans.

It’s always a good idea to check with your airline for the most accurate and up-to-date information regarding your specific flight.

Pre-Flight Factors That Add Time

Airport Check-in and Security

Before taking off, passengers must go through various pre-flight procedures, which can add time to the overall duration of a flight. One of the factors that contribute to this is airport check-in and security.

Passengers are required to arrive at the airport well in advance to complete the check-in process, which involves verifying identification, collecting boarding passes, and checking in luggage. This process can take anywhere from 30 minutes to an hour, depending on the airline and the number of passengers.

Once checked in, passengers must then go through airport security, which includes passing through metal detectors, scanning bags, and sometimes even going through body scanners. These security measures are in place to ensure the safety of all passengers and can add additional time to the pre-flight process.

It is important for passengers to be aware of any specific security requirements or restrictions, such as liquids or electronic devices, to avoid any delays.

Passengers should also consider the size and busyness of the airport, as larger airports with higher passenger volumes may require more time for check-in and security. It is always recommended to check with the airline and arrive at the airport with ample time to complete these pre-flight procedures to avoid any unnecessary stress or delays.

Boarding the Plane

Once passengers have completed the check-in and security procedures, the next step is boarding the plane. Boarding processes can vary depending on the airline and the type of aircraft being used. Some airlines follow a zone-based boarding system, where passengers are called to board in groups based on their seat location or ticket class.

This is done to ensure a smooth and efficient boarding process.

However, boarding a plane can still take some time, especially if there are delays or if passengers are not following the instructions given by the airline staff. It is important for passengers to pay attention to announcements and be ready to board when their zone or row is called.

Being prepared with all necessary documents, such as boarding passes and identification, can help expedite the boarding process.

Passengers should also be mindful of their carry-on luggage and ensure that it meets the airline’s size and weight restrictions. If a passenger’s carry-on luggage is deemed too large or overweight, they may be asked to check it in, which can further add to the boarding time.

In-Flight Factors That Add Time

When it comes to flying a plane, there are several factors that can add to the overall flight time. These factors can vary depending on various circumstances, such as the airport, weather conditions, and the specific aircraft being used.

Here are some of the in-flight factors that can contribute to a longer flight duration:


Before a plane can take off, it must first taxi from the gate to the runway. Taxiing can take several minutes, especially at larger airports with multiple runways. Factors such as air traffic and the distance between the gate and the runway can affect the amount of time spent taxiing.

In some cases, planes may have to wait in a queue before taking off, which can further add to the overall flight time.

Ascent and Descent

During the ascent and descent phases of a flight, the plane is either climbing or descending to its cruising altitude. The rate at which a plane climbs or descends can vary depending on factors such as air traffic, air traffic control instructions, and weather conditions.

In certain situations, planes may need to fly at a lower altitude due to turbulence or other safety concerns, which can increase the overall flight time.

Cruising Altitude and Speed

Once a plane reaches its cruising altitude, it can maintain a steady speed and altitude for the majority of the flight. However, factors such as air traffic, weather conditions, and flight restrictions can sometimes require pilots to adjust their altitude or speed.

These adjustments may be necessary to avoid congestion, adverse weather, or restricted airspace. While these changes are made to ensure safety, they can contribute to a longer flight time.

Aircraft Type

The type of aircraft being used can also impact the overall flight time. Different aircraft have varying capabilities, including speed, range, and fuel efficiency. For example, larger aircraft may require more time to reach their cruising altitude or may have a lower cruising speed compared to smaller aircraft.

Additionally, certain aircraft may also have to make more frequent stops for refueling, which can further extend the total flight duration.

It’s important to note that while these in-flight factors can add time to a flight, they are necessary for ensuring safety and adhering to air traffic control regulations. Pilots are trained to prioritize the well-being of passengers and crew, and they will take the necessary steps to ensure a smooth and safe flight, even if it means a slightly longer journey.

Post-Flight Factors That Add Time


Once a plane lands, the process of deplaning, or getting off the aircraft, begins. The time it takes to deplane can vary depending on several factors. One of the main factors is the size of the aircraft and the number of passengers on board.

Larger planes with more passengers may take longer to deplane as there are more people to navigate through the aisles and disembark. Additionally, the efficiency of the airline and its crew plays a role in how quickly passengers can exit the aircraft.

Some airlines have streamlined deplaning procedures, while others may take longer due to various reasons such as lack of personnel or technical issues. It is not uncommon to experience delays during the deplaning process, especially on busy flights or when there are unforeseen circumstances such as bad weather or mechanical problems.

Baggage Claim and Customs

After deplaning, passengers must proceed to the baggage claim area to retrieve their checked luggage. The time it takes to collect baggage can vary depending on a few factors. Firstly, the size of the airport and the number of flights arriving at the same time can affect the wait time at the baggage claim area.

Busy airports may have longer wait times due to the sheer volume of baggage being handled. Additionally, the efficiency of the airline and baggage handlers can impact the time it takes for luggage to be brought to the carousel.

Some airlines have implemented advanced baggage handling systems to expedite this process, while others may still rely on manual labor.

Once passengers have collected their baggage, they may need to go through customs. This process involves declaring any items that need to be declared and going through security checks. The time it takes to clear customs can vary depending on the airport and the number of passengers going through the process.

Some airports have implemented automated customs procedures, such as self-service kiosks, which can help speed up the process. However, it is important to note that customs procedures can be time-consuming, especially if there are long queues or if passengers have items that need further inspection.


In summary, calculating exactly how long a flight will take depends on many variables. While the average flight time gives you a general idea, factors like aircraft type, weather, and air traffic can all affect the duration of your journey.

The next time you’re planning a trip, be sure to account for all the pre-flight, in-flight, and post-flight factors that add time to your total travel. This will help ensure you schedule adequate time for your entire airport experience!
