Visualizing the U.S. Airports with the Worst Flight Delays

They say good things come to those who wait. In the case of flight passengers, however, some may be waiting much longer than others.

With frequent flights comes frequent problems. Unexpected travel irritations, delays, and cancellations are all common issues faced by flyers the world over. Correspondingly, certain airports have developed a reputation for making their passengers wait.

Today’s interactive chart from USAFacts shows the percentage of flights delayed, as well as the average length of those delays, at U.S. airports between October 2018 and September 2019.

The Top 10 Airports With the Longest Delays

In the worst airports across the country, over 25% of all flights get delayed. Here is a list of the top offenders based on percentage of flights delayed and the average delay, according to flight data.

#8DenverDenver International21.6%15.3 minutes
#9MiamiMiami International21.6%15.3 minutes
#10ChicagoChicago Midway22%13.4 minutes

Newark Liberty International takes the top spot, with 26.5% of all flights taking off late. To make matters worse, it also had the longest average delay time, at 22 minutes per flight. The runner-up is another New York-based airport, LaGuardia, averaging close to 20 minutes per flight delay.

The third worst offender was Chicago O’Hare International airport, where over a quarter of flights arrived late, with an average delay of 19 minutes. Chicago O’Hare International saw more flights than Newark and LaGuardia combined, making average delays more costly.

What’s Behind These Major Flight Delays?

While the New York area hosts two of the worst airports in the country, flight delays are exacerbated by a number of regional factors.

First, it hosts one of the busiest air corridors worldwide. As a result, any unexpected interruption or delay has an outsized effect on flights arriving at their destination on time.

Coupled with this is the commanding presence of United Airlines. As one of the largest airlines in the world, it operates over 401 daily flights at Newark airport. Additionally, United has been known to have operational issues. For example, in June 2019, significant aircraft problems led the Newark airport to suspend flights altogether.

There are four major causes of flight delays: poor weather conditions, late aircraft, carrier related (such as baggage, fueling, or maintenance problems), and airspace system issues.

cause of airport flight delays

According to this data, it’s clear that late aircraft is the most prevalent cause for flight delays that ended up being longer than 15 minutes.

Late aircraft creates a domino effect: when an airplane arrives late at an airport, a following flight that uses the same aircraft will depart behind schedule. In peak months such as July, this contributes to nearly 50% of flight delays.

Worst Months of the Year to Fly

The number of flights on U.S. airlines has more than tripled, from 275 million flights in 1978 to 889 million in 2018.

Along with this, flight activity is typically highest in the summer—coinciding with July’s highest average flight delay of 76 minutes. Months in the summer followed suit, with June averaging 72 minutes per delay and August having an average delay of 71 minutes, among flights that were delayed over 15 minutes.

April471
May570
February669
January

768
September867
March965

Perhaps surprisingly, flights in December bucked this trend. Even as a flight-heavy month, average long delays hovered around 60 minutes during the holiday season.

The 10 U.S. Airports with the Fewest Delays

By comparison, a number of airports appear to have avoided this trap. Data below shows the top airports in the U.S. with the fewest flight delays during the same time period.

#10Santa AnaJohn Wayne Airport-Orange County14.7%9.8 minutes

As the volume of air travel continues to climb, it is clear that some airports underperform others by a wide margin. To break the vicious cycle of delays, it will be vital for airports to get initial flights departing on time in the first place.

The Biggest Companies By Market Cap in 60 Countries

Tech giants are increasingly making up more of the Fortune 500, but the world’s biggest companies by market cap aren’t so cut and dry.

Despite accounting for the largest market caps worldwide—with trillion-dollar companies like Apple and contenders including Tencent and Samsung—tech wealth is largely concentrated in just a handful of countries.

So what are the biggest companies in each country? We mapped the largest company by market cap across 60 countries in August 2021 using market data from CompaniesMarketCap, TradingView, and MarketScreener.

What are the Largest Companies in the World?

The world has 60+ stock exchanges, and each one has a top company. We looked at the largest local company, since many of the world’s largest firms trade on multiple exchanges, and converted market cap to USD.

Many are former monopolies or massive conglomerates that have grown in the public space, such as South Africa’s Naspers and India’s Reliance Industries.

Others are local subsidiaries of foreign corporations, including Mexico’s Walmex, Chile’s Enel and Turkey’s QNB Finansbank.

But even more noticeable is the economic discrepancy. Apple and Saudi Aramco are worth trillions of dollars, while the smallest companies we tracked—including Panama’s Copa Group and Oman’s Bank Muscat—are worth less than $5 billion.

Finance and Tech Dominate The Biggest Companies By Market Cap

Across the board, the largest companies were able to accumulate wealth and value.

Some are newer to the top thanks to recent success. Canada’s Shopify has become one of the world’s largest e-commerce providers, and the UK’s AstraZeneca developed one of the world’s COVID-19 vaccines.

But the reality is most companies here are old guards that grew on existing resources, or in the case of banks, accumulated wealth.

Banks were the most commonly found at the top of each country’s stock market. Closely behind were oil and gas giants, mining companies, and former state-owned corporations that drove most of a country’s wealth generation.

But as more economies develop and catch up to Western economies (where tech is dominant), newer innovative companies will likely put up a fight for each country’s top company crown.

All World Languages, By Native Speakers

View a high resolution version of today’s graphic by clicking here.

Languages provide a window into culture and history. They’re also a unique way to map the world – not through landmasses or geopolitical borders, but through mother tongues.

The Tower of Babel

Today’s infographic from Alberto Lucas Lopez condenses the 7,102 known living languages today into a stunning visualization, with individual colors representing each world region.

Only 23 languages are spoken by at least 50 million native speakers. What’s more, over half the planet speaks at least one of these 23 languages.

Chinese dominates as a macrolanguage, but it’s important to note that it consists of numerous languages. Mandarin, Yue (including Cantonese), Min, Wu, and Hakka cover over 200 individual dialects, which vary further by geographic location.

CountryNative Chinese speakers (millions)
🇨🇳 China1,152.0
🇹🇼 Taiwan21.8
🇭🇰 Hong Kong SAR6.5
🇲🇾 Malaysia5.1
🇸🇬 Singapore1.8
🇹🇭 Thailand1.2
🇻🇳 Vietnam0.9
🇵🇭 Philippines0.7
🇲🇲 Myanmar0.5
🇲🇴 Macau SAR0.5
Other6.0
Total1,197 million

Chinese is one of the most challenging languages for English speakers to pick up, in part due its completely unfamiliar scripts. You’d have to know at least 3,000 characters to be able to read a newspaper, a far cry from memorizing the A-Z alphabet.

Spanglish Takes Over

After Chinese, the languages of Spanish and English sit in second and third place in terms of global popularity. The rapid proliferation of these languages can be traced back to the history of Spanish conquistadors in the Americas, and British colonies around the world.

Today, Spanish has 399 million native speakers, but these are mostly concentrated in Latin America. English has 335 million native speakers under its belt, with a widespread reach all over the globe.

Two Worlds, One Family

While the visualization makes all the world languages seem disparate, this linguistic family tree shows how they grew from a common root. It also explains how languages can evolve and branch out over time.

Language Tree

This linguistic tree also includes many languages that are not on the large visualization of 23 mother tongues. Some of them might be considered endangered or at risk today, such as Catalan or Welsh. However, with globalization, a few interesting linguistic trends are arising.

1. Language revival
Certain enclaves of marginalized languages are being preserved out of pride for the traditional and cultural histories attached.

While Catalan was once banned, its rebirth is a key marker of identity in Barcelona. More than 150 universities teach Catalan worldwide. In the case of Welsh, a mammoth university project plans to make sure it does not die out. Researchers are compiling ten million Welsh words to preserve the past, present, and future of the language.

2. Language forecast
At this point in time, English is the lingua franca – adopted as a common language among speakers with different mother tongues. However, this status might soon be fuzzier as demographic trends continue.

The rise of China is an obvious one to consider. As China continues to increase its economic might and influence, its languages will proliferate as well.

At the same time, 26 African countries are projected to double their current size, many of which speak French as a first language. One study by investment bank Natixis suggests that Africa’s growth may well bring French to the forefront – making it the most-spoken language by 2050.

Could French provide a certain je ne sais quoi that no other world language can quite replace?
