The global airline industry has faced a rollercoaster ride in recent years. While 2018 saw impressive growth with nearly $600 billion in revenue and an 8% rise in profits, the COVID-19 pandemic brought the industry to a near standstill in 2020 and 2021.

However, 2022 marked a significant comeback, with airlines generating an estimated $772 billion in revenue and returning to profitability with a modest $10.1 billion in operating income, despite continued pandemic disruptions. This rebound was driven by a surge in demand, particularly for domestic and leisure travel, as people embraced the opportunity to fly again after months of lockdowns and travel restrictions (Statista). While profits remain below pre-pandemic levels, the industry is on track for further recovery in 2024.

One of the things that has been notable in the past ten years is that the steady flow of air travel has continued to grow.

A few airlines have put themselves in the position to be considered the best airlines from around the globe. These are the top choices of many passengers and the airlines that you may want to familiarise yourself with if you have plans to travel the world.

Top 10 Largest Airlines in 2022-23

However, In this blog, we are looking at the largest airlines in the world by the number of passengers they carry globally.

1- American Airlines

PASSENGERS PER YEAR: 199.3 million

HEADQUARTERS’ LOCATION: Fort Worth, Texas, United States of America United States Flag

NUMBER OF HUBS: 9

SIZE OF FLEET: 965 aircraft

American Airlines

While American Airlines is already the most travelled airline, there is no reason to assume that it will not be dominating the airspace for years to come.

They have plans to increase their air fleet by more than 100 aircraft, which means that they will be offering more than their current 6,800 daily flights around the globe (gcs-web).

American Airlines is a part of the American Airlines Group, which is a result of American Airlines merging with U.S. Airways. The company had even filed for Chapter 11 bankruptcy in 2011.

It almost ruined them, but instead, they have continued to rise from their past misfortune. The company rose 25 spots in the Fortune 500.  Its revenue rose 64% to $49 billion in 2022, and the number of miles travelled by paying passengers rose 34% (fortune.com).

2- Delta Airlines

PASSENGERS PER YEAR: 171.4 million

HEADQUARTERS’ LOCATION: Atlanta, Georgia, United States of America United States Flag

NUMBER OF HUBS: 9

SIZE OF FLEET: 963

WEBSITE: Delta.com

Delta

Delta is considered to be the second world’s largest airline carrying passengers internationally to six continents and various destinations across the world. Delta’s headquarters is located in Hartsfield – Jackson Atlanta International Airport, which is one of the busiest airports in the United States and the world (Misachi).

Delta has grown into a global airline giant, now operating over 5,400 daily flights and serving 325 destinations in 52 countries across six continents (Delta Airlines).

Delta Airlines moved 28 spots up this year’s list to 85, thanks to a robust travel rebound in the wake of the COVID-era slowdown. Its operating revenue for the year reached $50.6 billion, up 69% from 2021 (Fortune.com).

3- Ryanair

PASSENGERS PER YEAR: 168.6 million

HEADQUARTERS’ LOCATION: Dublin, Ireland Ireland Flag

NUMBER OF BASES: 85

SIZE OF FLEET: 303

WEBSITE: Ryanair.com

Ryanair

Ryanair is based in Ireland, and it’s the third-largest airline in Europe. Ryanair covers a lot of airspaces and offers flights to 400 destinations in 41 countries, which are located throughout Europe, Africa, and the Middle East (Misachi). They are operating an average of 2400 flights daily (FlightConnections).

Ryanair works to keep prices affordable and follows some of the other airlines on this list in that some of their practices have helped reduce the overall cost of operations. One of these is that they use mostly one model of plane, which helps to reduce the number of different expenses.

This airline has a mixed reputation. It is very ‘low frills,’ which means that you will not be getting any extras as they have cut all of those to keep the prices as low as possible (Levin).

Ryanair Holdings ranks 315 with $11.2 billion in revenue (up 101.1%). The Ireland-headquartered airline has 22,261 employees and made a profit of $1.4 billion (Fortune.com).

4- United Airlines

PASSENGERS PER YEAR: 144.3 million

HEADQUARTERS’ LOCATION: Chicago, Illinois, United States of America United States Flag

NUMBER OF HUBS: 8

SIZE OF FLEET: 944

WEBSITE: United.com

United Airlines

United Airlines was founded under the name Varney Air Lines in 1926. Today, they operate a fleet of 944 aircraft (airfleets.com ).

United Airlines offers some of the most popular international and domestic flights in the United States. They are known for their comfort and being a great airline to work with if you have customer service issues.

Today, United’s wings stretch far beyond its North American home base, encompassing an impressive 6,700-7000 daily flights across six continents and 171 destinations in 51 countries (United Airlines).

One of the things that they are not great with is fares. United Airlines tickets are often more expensive than their competitors, but their customer service is great enough that many people choose to only fly United.

One interesting fact about United Airlines’ past is that the flight attendants, at one time, were all trained nurses who were able to provide care if someone had an emergency medical situation while on the plane (Tracy).

United Airlines, one of the largest American airline carriers by revenue, has jumped 50 spots on this year’s Fortune 500, securing a spot within the top 100. The Chicago-based company benefited from the post-COVID travel rebound, bringing in $45 billion in revenue in 2022, an 83% increase from 2021 (Fortune.com).

5- Southwest Airlines

PASSENGERS PER YEAR: 126.6 million

HEADQUARTERS’ LOCATION: Dallas, Texas, United States of America United States Flag

NUMBER OF HUBS: 11

SIZE OF FLEET: 821

WEBSITE: Southwest.com

Southwest Airlines

Southwest Airlines was founded in 1966 and has been growing ever since. Today, they offer flights to 101 destinations with aircraft flying to 40 of the states in America (Misachi).

One of the things that makes Southwest so successful is its unique business model, which deserves some attention. They choose to purchase only one type of plane for their entire fleet. They chose the aircraft model Boeing 737.

This allows them to cut costs when trying to outfit their planes as everything fits the same way inside. This also helps with cutting costs to service the plane and in being able to find qualified mechanics, as they only need to be experts in this one Boeing aircraft model (Fleming).

While they are not the number one airline, there are many things that they have done well. Southwest Airlines started as a small company in 1971, and since then, they have grown to be one of the top airlines in the entire world.

While Southwest doesn’t officially publish its daily flight count, industry estimates suggest it operates around 4,000 flights daily. This vast network, combined with its unique approach, has cemented Southwest’s position as the world’s largest low-cost carrier and a beloved brand among millions of travellers.

The company continues to see an increase in its profits and the number of passengers carried each year. Southwest has also been ranked 164th by Fortune Magazine. The company has won many industry awards for its customer service, safety, and environmental standards (Fortune.com).
