Worst airport for runway delays
New York's John F. Kennedy International Airport, commonly known as JFK Airport, has been consistently ranked as one of the worst airports in the United States, with runway delays being a significant factor contributing to this negative reputation.
A study by AirAdvisor in 2023 revealed that JFK Airport had the worst CDF (Chronically Delayed Flights) score of almost 62%. This means that a significant proportion of flights departing from or arriving at JFK are consistently delayed. The issue of delays at JFK Airport is so prevalent that it has been advised that passengers consider using neighbouring airports like LaGuardia or Newark to avoid potential delays.
There are several factors that contribute to the runway delays at JFK Airport. Firstly, the airport itself is incredibly busy, serving over 55 million passengers annually with over 70 airlines operating routes in and out of its four runways. The high volume of flights and passengers can lead to congestion and delays, especially when there are staffing issues, which is a common challenge at JFK. This includes a shortage of flight attendants, baggage handlers, and security officers, resulting in long lines for check-in and security, further contributing to runway delays as planes wait for passengers.
The layout of JFK Airport also plays a part in the delays. The terminals are isolated from one another, making it difficult for passengers to reach their connecting flights on time. This, in turn, delays the departure of those flights, impacting the overall efficiency of runway operations.
In recent years, there have been efforts to address the issues at JFK Airport. The Port Authority has invested billions of dollars in overhauling the airport's infrastructure, including demolishing and renovating terminals to create modern and efficient facilities. The transformation of JFK Airport is expected to be completed by the end of the decade, with the goal of improving the overall passenger experience and reducing delays.
Despite these ongoing improvements, JFK Airport still faces challenges, and as of May 2024, it continues to be ranked as one of the worst airports for runway delays in the United States.

Long lines due to staffing issues
Long lines at JFK airport are often caused by staffing issues. With over 55 million annual passengers in 2022, JFK is the busiest airport in New York City. The high volume of passengers makes it difficult to find enough staff, including flight attendants, baggage handlers, and security officers. This results in long lines for check-in and security, causing delays for passengers and flights.
The issue of understaffing is not unique to JFK, as US airports are generally known for their long immigration lines. However, international travellers have noted that other countries, such as Canada, seem to manage their lines more efficiently despite having stricter interview processes.
The long lines at JFK have been a persistent issue, with some passengers reporting having to queue for 2 hours for passport control. The airport's terminals are also isolated from one another, making it challenging for passengers to reach their connecting flights on time, further contributing to delays.
To address the issue of delays, the Port Authority is investing $19 billion in overhauling JFK airport, including renovating and expanding terminals to increase efficiency. The transformation project includes the redevelopment of Terminal 6, the construction of a new 2.5-million-square-foot Terminal 1, and improvements to the airport's roadway network. These efforts aim to improve the overall experience and reduce the long lines caused by staffing shortages.
JFK's full transformation is expected to be completed by the end of the decade, with Terminal 1 projected to open for international flights in June 2026. The improvements aim to enhance the efficiency and capacity of the airport, reducing the impact of staffing shortages on the length of lines.

Poor terminal conditions
John F. Kennedy International Airport, more commonly known as JFK Airport, has long been notorious for its poor terminal conditions. The airport's terminals have been described as "dilapidated", with crowded gate areas, slow-moving security lanes, dingy concourses, and cramped hallways. The traffic situation in and around the terminals is also less than ideal, with passengers complaining about the difficulty in getting to connecting flights on time due to the terminals being isolated from one another.
The poor terminal conditions at JFK have resulted in significant delays for passengers. In fact, according to a study, more than one out of five flights at JFK are delayed by at least 15 minutes, and nearly 3% of flights are canceled. These delays have earned JFK the distinction of being the worst airport in the United States for runway delays.
The root causes of these issues can be attributed to a combination of high passenger volume, staffing shortages, and a lack of investment in infrastructure. With over 55 million annual passengers in 2022 alone, JFK is the busiest airport in New York City. This volume of passengers strains the airport's resources, including the availability of flight attendants, baggage handlers, and security officers. As a result, passengers often experience long lines and delays in checking in, getting through security, and claiming their luggage.
Recognizing the need for improvement, the Port Authority of New York and New Jersey has embarked on a massive redevelopment project for JFK Airport. The project, valued at over $19 billion, includes the demolition and renovation of several terminals, the expansion of existing terminals, and the construction of a new 2.5-million-square-foot Terminal 1, expected to open for international flights in June 2026. The goal is to transform JFK's terminals into modernized gateways to New York City, with improved facilities and customer service.
While the ongoing redevelopment project is a step in the right direction, it has not come without its own set of challenges. Community leaders and elected officials have raised concerns about the transparency of the project's finances and the inclusion of minority- and women-owned business enterprises (MWBEs). There have been calls for more data on the rate of hiring individuals from the local community and contracting MWBEs. Despite these concerns, the Port Authority remains committed to meeting its diversity goals and driving billions of dollars to MWBEs.

Inefficient terminal layout
JFK Airport in New York has been ranked the worst airport in the US for delays, with over one out of five flights delayed by at least 15 minutes and nearly 3% of flights being cancelled. The airport's terminals are isolated from one another, making it difficult for passengers to reach connecting flights on time. This causes delays for planes, as they have to wait for passengers.
JFK's inefficient terminal layout has been a significant contributor to the airport's poor reputation. The airport covers 5,000 acres in Queens and has five passenger terminals serving over 70 airlines. The vast space and multiple terminals can make navigating the airport challenging for passengers, especially those with connecting flights. The isolation of the terminals from each other exacerbates the issue, as passengers may struggle to reach their gates on time, leading to further delays.
The Port Authority has recognised the need for improvement and is investing $19 billion in overhauling JFK Airport, including demolishing and renovating terminals to modernise the airport and improve efficiency. The recent redevelopment of Terminal 6, which cost $4.2 billion, aimed to connect it with Terminal 5, enhancing the flow of passengers between gates. Construction has also begun on a new 2.5-million-square-foot Terminal 1, with private financing of $9.5 billion, which is expected to open for international flights in June 2026.
In addition to terminal improvements, the Port Authority is also working on a rebuilding project for the airport's roadway network, including new garages and electrical substations. These enhancements aim to improve traffic flow and accessibility within the airport grounds, reducing the time it takes for passengers and staff to move between terminals and improving the overall efficiency of the airport's operations.
The transformation of JFK Airport is a massive undertaking, and it is expected to be completed by the end of the decade. With these improvements, the airport aims to enhance the passenger experience, reduce delays, and improve its reputation as one of the worst airports for delays.

Long immigration lines
The problem is not unique to JFK, as US airports, in general, have a reputation for lengthy immigration lines. However, the issue is particularly pronounced at JFK, with some passengers reporting wait times of up to two hours just to get through passport control.
The long lines at JFK can be attributed to several factors. Firstly, the airport's terminals are isolated from one another, making it difficult for passengers to navigate between them and causing delays in getting to connecting flights. This layout also impacts the efficiency of immigration and security processes, as passengers may need to travel between different terminals to reach the appropriate checkpoints.
Additionally, JFK struggles with staffing issues, including a shortage of flight attendants, baggage handlers, and security officers. This shortage contributes to the long lines, as there are not enough staff members to process the high volume of passengers efficiently.
The combination of high passenger volume, terminal layout, and staffing shortages results in long immigration lines at JFK, causing frustration and delays for travellers. These issues have contributed to JFK's reputation as one of the worst airports in the United States for overall experience and chronic flight delays.
