While the Covid-19 pandemic continues to wreak havoc on the airline industry internationally, many airlines in 2019 saw substantial growth within their companies. Though first and second quarter reports give a false sense of which airlines are truly the largest in the world, viewing growth from a non-Covid-19 related perspective gives the consumer a better understanding on which airlines truly are the largest.
1. Delta Airlines
According to Delta Airlines financial reports, revenue in 2019 was $47 billion. According to Planespotters.net, Delta Airlines carries a hefty fleet of 834 aircrafts. Their fleet carries a diverse range of aircraft types ranging from the various Airbus craft, the Boeing 717, 727, 737, and on. In fact, Delta has over 300 Boeing 737’s, where the average age of this craft on this fleet is 9.7 years old. The oldest craft on the fleet is the Airbus A320 is an average 25.2 years old and has 69 still in use.
In 2019, the WATS (World Air Transport Statistics) reported that Delta Airlines carried 330,034 passengers. Now while this number is smaller than its competition (American Airlines), you can see that overall revenue and fleet size is what makes Delta the leader in the industry.
2. American Airlines
Again, the WATS (World Air Transport Statistics) reported that American Airlines carried 330,577 passengers.
When it comes to fleet size American Airlines is has the largest fleet in the world with a total of 876 aircrafts with an anticipated 18 more to arrive, according to Planespotters.net. Like with Delta, American Airlines has a large amount of Boeing 737s. In fact, they own a whopping 389 of them with an average 10.3 years of age. Furthermore, the oldest aircraft on the fleet with an average age of 19.5 years is the Airbus A320.
3. United Airlines
Coming in at number 3 in total revenue, this airline totaled $43.24 billion in 2019. WATS reported a total of 329,562 passengers, which is not far behind its leading competitors. Fleet size of this operation comes as no surprise being so close in revenue and passenger count to the two airlines above. Planespotters.net once again brings us information regarding leading airline industry fleet specs with United Airlines contains a fleet size of over 806 aircrafts with another 69 planned and on order. However, different than the larger airlines, their fleet has a much more narrow diversity of aircrafts than its leading competitors with much older averages for aircraft age. Being the oldest aircrafts on the fleet, the Airbus A320 averages 22.2 years and the Boeing 767 at 23.1 years old.
4. Deutsche Lufthansa Airlines
This airline out of Germany total revenue in 2019 was $40.79 billion. While the top three airlines on this list could potentially be debated as which should be listed as first through third when looking at all aspects (revenue, fleet, and passengers), Deutscha Lufthansa Airlines definitely comes in at a solid number four. In 2019, WATS reported a total of 158,986 passengers, in contrast to the leaders who each carried over 300,000 passengers in the same year.
5. Air France – KLM
While this airline is placed at number 5 on this list with a total revenue in 2019 was $30.45 billion, the amount of passengers that was carried last year is jaw dropping. According to the Airfrance KLM Group, this airline carried 104 million passengers in 2019! These 104 million passengers reached 250 destinations in 112 different countries.
