The last 12 months have been filled with highs and lows for the airline industry.

On the one hand, established players like Delta Air Lines and United Airlines have seen strong growth, customer loyalty, and new opportunities in some cases, setting records. Even some budget airlines like Norwegian Air have seen headwinds dying down, stabilizing finances, and an end to maintenance disasters.

On the other hand, the past two years have been a bloodbath. Tons of airlines have gone out of business, some of which were well-known around the world.

Bankruptcies caused by flawed business models, tight competition, bad management, and unexpected costs caused them to shutter operations and, in some cases, go into administration and completely sell off assets.

Costs associated with the Boeing 737 Max grounding and required inspections and repairs on certain Boeing 787 Dreamliner engines were another pain point.

"2019 has seen the fastest growth in airline failure in history," airline consulting firm IBA told Reuters last October.

The year 2020 looks to be off to a similar start, with Tuesday's news that Air Italy will shutter less than two years after starting operations.

Here are the commercial airlines that have been forced to close their doors and fold up their wings.
