• Demand for air travel has plummeted globally as the coronavirus pandemic continues to spread.
• Airlines are still operating at a reduced capacity, but they've grounded large portions of their fleets. They are routinely sending up planes with just one or two passengers, plus some cargo.
• We looked at data that shows just how empty the skies are these days, and what that drop means for air traffic around the world.

The airline industry is undergoing the worst crisis in its history.

What three months ago looked like a possible minor headwind for first-quarter earnings has morphed, in just weeks, into a crisis with a great impact than the terror attacks of September 11, 2001, the 2008 financial crash, and virtually every other history altering event of the jet age combined.

The situation has become especially dire as new forecasts and models predict that it will be months, or possibly even years, before life returns to normal.

"This is the biggest crisis that the industry has ever faced," Alexandre de Juniac, director general of the International Air Transport Association (IATA) said in a statement. "The impact on aviation has left airlines with little to do except cut costs and take emergency measures in an attempt to survive in these extraordinary circumstances."

IATA, which represents about 290 airlines around the world, has said that the airline industry could lose $314 billion dollars due to the outbreak.

Airlines around the world have grounded large parts of their fleets, and suspended numerous flights and routes – United Airlines, for instance, said it had decreased its capacity by 90% for the May schedule.

However, there are still flights in the air. While many of them are mostly empty, airlines are maintaining essential connectivity amid the pandemic — something the US requires as part of a government aid package delivered to the industry.

Many passenger flights are also carrying freight in their cargo holds, and some are adapting planes to carry cargo in empty passenger cabins. Essential workers, such as volunteer healthcare providers and public health officials are also still flying, and cargo-only operators are moving supplies such as masks, ventilators, and more, keeping supply chains intact.

Still, the skies are much emptier than they used to be.

We've analyzed flight data from OAG, an aerospace data and consulting company, to see the real time impact of the coronavirus on air traffic. We've also looked at data from the Transportation Security Administration (TSA), and from FlightRadar24, a service that tracks global air traffic.

The data show just how quiet the skies have become, even as flights continue at reduced rates. Keep reading to see what the falloff looks like.
