The airport is one of the busiest in the US and the world

Salt Lake City International Airport (SLC) is one of the busiest airports in the US and the world. In 2024, SLC was the 23rd busiest airport in the US and 86th busiest in the world in terms of passenger numbers, serving a record 28,364,610 passengers. SLC is also ranked as the 28th busiest airport in the world in terms of aircraft operations.

SLC is a major hub for Delta Air Lines, with the airline operating a reservations centre at the airport. Delta Air Lines accounts for about 70% of total traffic at SLC. The airport serves as a major gateway to the Intermountain West and West Coast, with 343 scheduled nonstop airline departures per day to 93 cities in North America and Europe. SLC is also within a 30-minute drive of nearly 1.3 million jobs.

The airport's convenient location and efficient operations contribute to its high volume of traffic. SLC is located about 4-5 miles from downtown Salt Lake City, providing easy access to the city centre. Additionally, SLC has consistently ranked high for on-time departures and arrivals and has the fewest flight cancellations among major US airports.

SLC has undergone a significant redevelopment program with a $5.1 billion investment to enhance its capacity and facilities. The new airport, which opened in phases starting in 2020, features modern terminals, concourses, and improved infrastructure. The expansion has increased the number of gates, improved passenger processing efficiency, and enhanced the overall travel experience.

With its high passenger traffic, efficient operations, and continuous development, SLC solidifies its position as one of the busiest airports in the United States and worldwide.

It has a strong on-time performance record

Salt Lake City International Airport has a strong on-time performance record. In April 2017, the airport ranked first for on-time departures and arrivals and for the percentage of cancellations among major US airports.

The airport's on-time performance is impressive given its size and the volume of flights it handles. The airport is the 23rd busiest airport in the United States and 86th busiest in the world, with more than 330 flights departing daily to 100 nonstop destinations. In 2024, the airport served a record 28.3 million passengers.

The airport's on-time performance can be attributed to several factors, including efficient management and operations. The airport is operated and managed by the Salt Lake City Department of Airports, which aims to provide quality transportation facilities and services to optimise convenience, safety, and efficiency for its customers.

Additionally, the airport's layout and infrastructure contribute to its on-time performance. The airport has four runways, three for commercial aircraft and one for general aviation. The runways are oriented in a NNW/SSE magnetic direction due to consistent prevailing winds, allowing for efficient take-offs and landings. The airport also has a single terminal with two concourses, connected by underground tunnels, which streamline the passenger flow and reduce travel distances.

The airport's strong on-time performance record enhances its reputation as a major hub for Delta Air Lines, which accounts for about 70% of its total traffic. The airport's efficient operations and convenient location, just 15 minutes from the city's convention centre and downtown hotels, make it an attractive option for travellers.

The airport is undergoing a multi-billion-dollar redevelopment

Salt Lake City International Airport is undergoing a multi-billion-dollar redevelopment, which began in July 2014 and is expected to be completed by 2026. The project has a budget of $5.1 billion, although one source states $4.1 billion, and is one of the largest construction projects in Utah's history. The airport is being built from the ground up, with entirely new international airport terminals and concourses.

The redevelopment is designed to meet Salt Lake City's needs for decades to come and is adaptable to the ever-changing aviation industry. The new terminal is more efficient, eliminating bottlenecks and reducing delays for passengers. It is also designed with sustainability in mind, aiming for a LEED Gold certification, and has achieved high environmental standards with features such as energy-efficient lighting and mechanical systems, waste minimization, and water conservation.

The new airport is also more accessible, with a rental car centre, a parking garage, and an elevated roadway. The construction of two linear concourses will provide a total of 93 gates, two tunnels, and an underground mid-field tunnel connection. The airport will also have improved security and will meet modern earthquake safety standards.

The project is being funded by various sources, including airport funds, passenger and customer facility charges, bonds, and federal grants. Notably, no local taxpayer dollars will be used for the airport redevelopment.

It has a capacity of 34 million passengers per year

Salt Lake City International Airport has a capacity of 34 million passengers per year. This is a significant increase from the 26,952,754 passengers served in 2023, and the record-breaking 28,364,610 passengers who travelled through the airport in 2024. The airport is currently undergoing a $5.1 billion redevelopment program, which will see the addition of new facilities and infrastructure to accommodate this large capacity.

The airport's ranking as the 20th busiest airport in the country with about 10.8 million boardings in 2021, and its position as the 23rd busiest airport in the United States and 86th busiest in the world, further emphasise the need for such a large capacity. The airport serves as a major hub for Delta Air Lines, with the airline operating a reservations centre headquartered at the airport.

The new airport, which opened in 2020, is a state-of-the-art facility boasting a $4.1 billion price tag. It is the largest public works project in Utah's history and the first new hub airport built in the United States in the 21st century. The airport features a central terminal building, two linear concourses, a nearly 1,000-foot-long passenger tunnel, and a total of 94 gates upon completion.

The redevelopment program is being funded by user fees, primarily from airlines serving the airport, as well as savings, car rental fees, passenger facility charges, and airport revenue bonds. No local tax dollars are being spent on the project. The project has achieved LEED Gold certification for its sustainable design strategies, which minimise the airport's environmental impact.

With a capacity for 34 million passengers per year, the new airport positions Salt Lake City for economic growth as an increasingly popular destination for both tourism and business. The airport's convenient location, efficient design, and high-quality facilities contribute to its appeal as a gateway to the Intermountain West and West Coast.
