Airport operations are extremely complex, with a complicated system of aircraft support services, passenger services, and aircraft control services contained within the operation. Thus airports can be major employers, as well as important hubs for tourism and other kinds of transit. Because they are sites of operation for heavy machinery, a number of regulations and safety measures have been implemented in airports, in order to reduce hazards. Additionally, airports have major local environmental impacts, as both large sources ofair pollution,noise pollution and other environmental impacts, making them sites that acutely experience theenvironmental effects of aviation. Airports are also vulnerable infrastructure toextreme weather,climate change caused sea level rise and other disasters.

In colloquial use in certain environments, the termsairport andaerodrome are often interchanged. However, in general, the termairport may imply or confer a certain stature upon the aviation facility that otheraerodromes may not have achieved. In some jurisdictions,airport is a legalterm of art reserved exclusively for those aerodromes certified or licensed as airports by the relevantcivil aviation authority after meeting specified certification criteria or regulatory requirements.[6]
That is to say, all airports are aerodromes, but not all aerodromes are airports. In jurisdictions where there is no legal distinction betweenaerodrome andairport, which term to use in the name of an aerodrome may be a commercial decision. In US technical/legal usage,landing area is used instead ofaerodrome, andairport means "a landing area used regularly by aircraft for receiving or discharging passengers or cargo".[7]
Smaller or less-developed airfields, which represent the vast majority, often have a single runway shorter than 1,000 m (3,300 ft). Larger airports for airline flights generally have paved runways of 2,000 m (6,600 ft) or longer. Skyline Airport inInkom, Idaho, has a runway that is only 122 m (400 ft) long.[8]
As of 2009[update], theCIA stated that there were approximately 44,000 "airports or airfields recognizable from the air" around the world, including 15,095 in the US, the US having the most in the world.[9][10]
Many US airports still lease part or all of their facilities to outside firms, who operate functions such as retail management and parking. All US commercial airport runways are certified by the FAA[11] under theCode of Federal Regulations Title 14 Part 139, "Certification of Commercial Service Airports".[12]
TheAirport & Airway Trust Fund (AATF) was created by theAirport and Airway Development in 1970 which finances aviation programs in the United States.[13]Airport Improvement Program (AIP), Facilities and Equipment (F&E), and Research, Engineering, and Development (RE&D) are the three major accounts ofFederal Aviation Administration which are financed by the AATF, as well as pays for the FAA's Operation and Maintenance (O&M) account.[14] The funding of these accounts are dependent on the taxes the airports generate of revenues.Passenger tickets,fuel, andcargo tax are the taxes that are paid by the passengers and airlines help fund these accounts.[15]
Airports revenues are divided into three major parts:aeronautical revenue, non-aeronautical revenue, and non-operating revenue. Aeronautical revenue makes up 50% in 2021 (from 54% and 48% in 2019 and 2020, non-aeronautical revenue makes up 34% (40%, 39% in previous years), and non-operating revenue makes up 16% (6%, 14%) of the total revenue of airports.[16]
Aeronautical revenue are generated through airline rents and landing, passenger service, parking, and hangar fees. Landing fees are charged per aircraft for landing an airplane in the airport property.[17]Landing fees are calculated through the landing weight and the size of the aircraft which varies but most of the airports have a fixed rate and a charge extra for extra weight.[18] Aircraft parking is also a major revenue source for airports. Aircraft are parked for a certain amount of time before or after takeoff and have to pay to park there.[19] Every airport has its own rates of parking, for example,John F Kennedy airport in New York City charges $45 per hour for a plane of 100,000 pounds and the price increases with weight.[20]
Non-aeronautical revenue is gained through things other than aircraft operations. It includes lease revenue from compatible land-use development, non-aeronautical building leases, retail and concession sales, rental car operations, parking and in-airport advertising.[21] Concession revenue is one big part of non-aeronautical revenue airports makes throughduty free, bookstores, restaurants and money exchange.[19] Car parking is a growing source of revenue for airports, as more people use theparking facilities of the airport.O'Hare International Airport in Chicago charges $2 per hour for every car.[22]
Many airports are local monopolies. To prevent them from abusing their market power, governments regulate how much airports may charge to airlines, usingprice-cap regulation.[23][24]
Airports are divided into landside and airside zones. The landside is subject to fewerspecial laws and is part of the public realm, while access to the airside zone is tightly controlled. Landside facilities may include publicly accessibleairport check-in desks, shops and ground transportation facilities.[25]
Most major airports provide commercial outlets for products and services. Most of these companies, many of which are internationally known brands, are located within the departure areas. These include clothing boutiques and restaurants and in the US amounted to $4.2 billion in 2015.[27] Prices charged for items sold at these outlets are generally higher than those outside the airport. However, some airports now regulate costs to keep them comparable to "street prices". This term is misleading as prices often match themanufacturers' suggested retail price (MSRP) but are almost never discounted.[28]
Many new airports include walkthrough duty-free stores that require air passengers to enter a retail store upon exiting security.[29]

Apart from major fast food chains, some airport restaurants offer regional cuisine specialties for those in transit so that they may sample local food without leaving the airport.[30]
Airport operations are made possible by an organized network of trainedpersonnel, specialized equipment, andspatial data. After thousands of ground operations staff left the industry during theCOVID-19 pandemic, there have been discussions on the need for systemic improvements in three primary areas:[citation needed]
Planes take-off and landinto the wind to achieve maximum performance. Because pilots need instantaneous information during landing, awindsock can also be kept in view of the runway. Aviation windsocks are made with lightweight material, withstand strong winds and some are lit up after dark or in foggy weather. Because visibility of windsocks is limited, often multiple glow-orange windsocks are placed on both sides of the runway.[32]
Each airport hires its own ground crew to process flights, cargo, passengers, and baggage. When a flight arrives, ramp services navigate a baggage cart to the aircraft. Bags are then sorted and transported by baggage handlers. Ramp services handle aircraft marshaling, the process in which aircraft arrive or depart from the gate. Once passengers and/or cargo is unloaded, a cleaning crew prepares the aircraft for its next flight by loading supplies and preparing other in-flight services. Ground crew will fuel the aircraft, and other visual inspections are conducted. Efficient work allows aircraft to have fast turnaround times of as little as 25 minutes.[33][34]
Like industrial equipment or facility management, airports require tailor-made maintenance management due to their complexity. With many tangible assets spread over a large area in different environments, these infrastructures must therefore effectively monitor these assets and store spare parts to maintain them at an optimal level of service.[35]
To manage these airport assets, several solutions are competing for the market:CMMS (computerized maintenance management system) predominate, and mainly enable a company's maintenance activity to be monitored, planned, recorded and rationalized.[35]

Aircraft noise is a major cause ofnoise disturbance to residents living near airports. Sleep can be affected if the airports operate night and early morning flights. Aircraft noise occurs not only from take-offs and landings but also from ground operations including maintenance and testing of aircraft. Noise can haveother health effects as well. Other noises and environmental concerns are vehicle traffic causing noise and pollution on roads leading to the airport.[36]
The construction of new airports or addition of runways to existing airports, is often resisted by local residents because of the effect on countryside, historical sites, and local flora and fauna. Due to the risk of collision between birds and aircraft, large airports undertake population control programs where they frighten or shoot birds.[37]
The construction of airports has been known to change local weather patterns. For example, because they often flatten out large areas, they can be susceptible to fog in areas where fog rarely forms. In addition, they generally replace trees and grass with pavement, they often change drainage patterns in agricultural areas, leading to more flooding, run-off and erosion in the surrounding land.[38][citation needed] Airports are often built on low-lying coastal land, globally 269 airports are at risk ofcoastal flooding now.[39] A temperature rise of 2oC – consistent with theParis Agreement – would lead to 100 airports being below mean sea level and 364 airports at risk of flooding.[39] If global mean temperature rise exceeds this then as many as 572 airports will be at risk by 2100, leading to major disruptions without appropriate adaptation.[39]
A 2019 report from the Cooperative Research Programs of the USTransportation Research Board showed all airports have a role to play in advancing greenhouse gas (GHG) reduction initiatives. Small airports have demonstrated leadership by using their less complex organizational structure to implement newer technologies and to serve as a proving ground for their feasibility. Large airports have the economic stability and staff resources necessary to grow in-house expertise and fund comprehensive new programs.[40]
A growing number of airports are installing solarphotovoltaic arrays to offset their electricity use.[41][42] TheNational Renewable Energy Lab has shown this can be done safely.[43] This can also be done on the roofs of the airports and it has been found that the solar panels on these buildings work more effectively when compared to residential panels.[44][clarification needed]
The world's first airport to be fully powered by solar energy is located atKochi, India.[45][46]
As a part of their sustainability efforts, more and more airports are starting to explore the consequences of more electric aircraft coming into service. Electric aircraft require much energy; operating 49 small 50-passenger short-range battery electric aircraft would demand at least 16 GWh/year,[47] and with short turnaround times between different flights, the charging powers have to be substantial. To tackle these issues, more airports are starting to look into alternative energy production such as solar power and wind power, but also how to use airport areas for biomass production.[48][49] Another solution investigated is to use energy storage to charge during the night and use to charge the aircraft during daytime.[49][50]
Airports, as major international travel hubs, have the potential to be significant transmission points for infectious diseases. A notable study conducted during the peak of the 2015–2016flu season at Helsinki-Vantaa airport in Finland revealed that commonly touched surfaces in airports, especially the plastic security screening trays, are highly susceptible to contamination by respiratory viruses. These trays are touched by hundreds of passengers daily and, being made of plastic, a non-porous material, provide an environment where viruses can survive for extended periods. In comparison, bathroom surfaces in the same airport tested negative for respiratory viruses, possibly indicating a heightened awareness of hygiene in these spaces.[51][52]
Hand hygiene plays a pivotal role in preventing the spread of infectious diseases in airports. Research indicates that only about 70% of individuals wash their hands after using the toilet, and of those, only 50% do so correctly. In airport settings, just one in five individuals maintain clean hands—defined as washing with soap for at least 15 seconds in the preceding hour. Given the frequent touching of shared surfaces in airports, such as trays, railings, and touch panels, this poses a significant risk for disease transmission. A study from theUniversity of Cyprus andMIT used models and simulations to demonstrate that increasing hand cleanliness from 20% to 30% in all airports could reduce the potential global impact of a disease by 24%. If cleanliness levels reached 60%, this impact could decrease by 69%. Focusing on just the top 10 most influential airports for disease spread, enhancing hand hygiene practices could still significantly reduce disease transmission rates from 45% to 37%. The findings underscore the importance of promoting hand-washing in airports as a key measure in preventing the global spread of diseases.[53][54]
The earliest aircraft takeoff and landing sites were grassy fields.[55]
Beijing Nanyuan Airport in China, which was built to accommodate planes in 1904, and airships in 1907, opened in 1910.[56] It was in operation until September 2019.Pearson Field Airport inVancouver, Washington, United States, was built to accommodate planes in 1905 and airships in 1911, and is still in use as of February 2024.[57]
Hamburg Airport opened in January 1911, making it the oldest commercial airport in the world which is still in operation.Bremen Airport opened in 1913 and remains in use, although it served as an American military field between 1945 and 1949.Amsterdam Airport Schiphol opened on September 16, 1916, as a military airfield, but has acceptedcivil aircraft only since December 17, 1920, allowingSydney Airport—which started operations in January 1920—to claim to be one of the world's oldest continuously operating commercial airports.[58]
Following the war, some of these military airfields added civil facilities for handling passenger traffic. One of the earliest such fields wasParis – Le Bourget Airport atLe Bourget, near Paris. The first airport to operate scheduled international commercial services wasHounslow Heath Aerodrome in August 1919, but it was closed and supplanted byCroydon Airport in March 1920.[59]
The malicious use of UAVs has led to the deployment ofcounter unmanned air system (C-UAS) technologies such as the AaroniaAARTOS which have been installed on major international airports.[60][61]
