Why So Many Airlines are Going Bankrupt

Watch Facts Elle's

Key takeaways

- Nine prominent European airlines collapsed between 2017 and 2019 while the global airline industry was enjoying record profits. Monarch, Air Berlin, Primera Air, Cobalt Air, Wow Air, Aigle Azur, XL Airways France, Adria Airways, and Thomas Cook failed during a five-year period when commercial airlines collectively earned more than $160 billion.

- Eight of those nine airlines collapsed in September or October because European aviation depends heavily on summer travel. Europe's winter passenger demand can fall to nearly half its summer level, whereas American airlines benefit from steadier business travel and less extreme seasonal fluctuations.

- Advance ticket sales can keep financially weak airlines alive until summer ends. Cash typically arrives between March and August, but when bookings decline in September, unpaid debts can trigger aircraft repossessions, flight cancellations, passenger compensation costs, and ultimately bankruptcy.

- Thomas Cook collapsed just five and a half hours after publicly assuring customers that flights were operating normally. On September 22, 2019, the airline was still selling tickets and boarding passengers, but by the early hours of September 23, its insolvency had stopped flights worldwide.

Thomas Cook: “our flights and holiday operations are operating as normal.”

Thomas Cook: “we are sorry to announce that Thomas Cook has ceased trading with immediate effect.”

- British aviation authorities positioned replacement aircraft before Thomas Cook officially collapsed. A Malaysia Airlines Airbus A380 flew empty from Kuala Lumpur to Manchester, arriving shortly after midnight on September 23, allowing repatriation flights to begin the same day and limiting some passenger delays to hours.

- One Airbus A380 replaced almost seven Thomas Cook A321s' worth of daily passenger capacity from Mallorca. Rather than finding separate aircraft for eight British destinations, authorities operated up to three daily Palma–Manchester flights carrying nearly 1,500 passengers combined, then used buses to distribute travelers to other cities.

- Five of the nine failed airlines had concentrated on low-cost, long-haul flying, a model vulnerable to rising fuel prices. Cheap fuel after 2014 encouraged aggressive expansion and discounted fares, but rising prices from 2017 forced airlines to choose between losing customers through fare increases or accepting worsening profitability.

- Excess aircraft capacity made Europe's seasonal aviation market increasingly difficult to survive. Years of strong profits and investor funding encouraged airlines to expand fleets for summer demand, leaving them paying for aircraft throughout the winter even when passenger numbers were insufficient to fill them.

- Commercial airlines earned more than $160 billion in combined profits over five years. The figure, which included a forecast for 2019, represented one of the most consistently profitable periods in aviation history. Yet several prominent airlines collapsed during those same years.

- Airline failures accelerated between 2017 and 2019 despite strong industry-wide profitability. The collapses included long-established national and leisure carriers, newer budget airlines, and companies operating substantial international networks.

- Monarch Airlines collapsed in 2017 after approximately 50 years of operations. The British leisure airline was a well-established carrier, making its closure an early prominent example of the industry's emerging problems.

- Air Berlin ceased operations in the same month as Monarch in 2017. The German airline employed more than 8,000 people and operated approximately 100 aircraft, demonstrating that even large European carriers were vulnerable.

- Primera Air collapsed in 2018 after pursuing low-cost transatlantic expansion. The airline had attracted attention with its budget long-haul services, but its ambitious business model failed to produce a sustainable operation.

- Cobalt Air, a smaller airline based in Cyprus, also ceased operations in 2018. Its failure added to the growing number of European airline closures.

- Wow Air collapsed in 2019 after becoming a major participant in the low-cost transatlantic market. Its failure highlighted the financial vulnerability of airlines attempting to compete internationally through unusually low fares.

- Aigle Azur, France's second-largest airline, ceased operations in 2019. Its collapse showed that the problems extended beyond small or newly established budget carriers.

- XL Airways France closed in 2019 after years of transatlantic operations. The airline's disappearance further reduced the number of European carriers serving long-distance leisure markets.

- Adria Airways, a mid-sized Slovenian airline, also stopped flying in 2019. Its closure reinforced the geographical concentration of airline failures in Europe.

- Thomas Cook Airlines collapsed in September 2019 after approximately 50 years in business. Its failure became the largest airline collapse in British history at the time, disrupting holiday travel for passengers around the world.

- All nine prominent airline failures examined were European. Monarch, Air Berlin, Primera Air, Cobalt Air, Wow Air, Aigle Azur, XL Airways France, Adria Airways, and Thomas Cook were all based in Europe. The concentration suggested that European aviation faced particular structural pressures.

- Eight of the nine airlines stopped flying in September or October. Wow Air was the sole exception. The recurring timing reflected the relationship between European airlines' seasonal revenue and their ability to meet financial obligations.

- Summer is generally the most profitable season for airlines because passenger demand increases significantly. Leisure travel, especially holiday travel, creates substantial revenue opportunities during the Northern Hemisphere summer.

- European air travel experiences much sharper seasonal fluctuations than American air travel. Europe's greater dependence on leisure passengers means winter traffic can fall to almost half its summer level.

- American passenger traffic typically peaks in August and reaches its lowest point in February. Smaller seasonal increases also occur around Thanksgiving and Christmas, but overall demand is more evenly distributed throughout the year than in Europe.

- Business travelers help stabilize demand for American airlines. The United States has a proportionally larger business-travel market, with passengers booking trips more consistently throughout the year. This reduces the amount of unused aircraft capacity during winter.

- Some Asia-Pacific aviation markets experience almost no significant seasonal variation. More consistent passenger demand allows airlines in these regions to avoid some of the extreme seasonal financial pressures experienced in Europe.

- Qantas benefits from serving both the Northern and Southern Hemispheres. Its substantial presence in markets with different summer seasons helps distribute passenger demand and earnings more evenly throughout the year.

- Ryanair's 2018 quarterly figures illustrate the importance of European summer travel. The video cited gross profit of $901 million for January–March, $1.4 billion for April–June, $2.1 billion for July–September, and $877 million for the final quarter.

- Ryanair generated substantially more gross profit during the middle of the year than during the surrounding quarters. The example demonstrated how a European airline can depend on a relatively short period to generate much of its annual earnings.

- Airlines receive much of their summer revenue before passengers actually fly. Tickets for summer holidays are frequently purchased months in advance, creating a substantial inflow of cash before the busiest travel period begins.

- March through August is a particularly important cash-generation period for European leisure airlines. Advance bookings for summer flights can provide enough money to sustain even airlines experiencing serious underlying financial difficulties.

- Cash flow can deteriorate sharply once September arrives. As summer bookings decline, airlines receive less new money while continuing to face debt payments, fuel expenses, aircraft costs, and other operating obligations.

- An airline can survive the summer and collapse shortly afterward without a sudden change in its underlying business model. Strong seasonal ticket receipts can temporarily conceal financial weakness that becomes impossible to manage when new bookings slow.

- Missing debt payments can trigger a destructive chain of operational failures. Aircraft may be repossessed, forcing flight cancellations and creating additional expenses for passenger accommodation, compensation or penalties, and alternative transportation.

- Aircraft repossessions can make an airline's financial problems progressively worse. Losing aircraft reduces its ability to operate revenue-generating flights, while cancellations create further liabilities. This can rapidly exhaust the remaining cash needed to keep the airline operating.

- The video identified limited bankruptcy restructuring opportunities in Europe as another contributor to abrupt airline closures. In contrast with the United States, where businesses have established mechanisms to continue operating during restructuring, European airline insolvencies were described as more likely to result in immediate shutdowns.

- Airlines can collapse exceptionally quickly because they are capital-intensive businesses with substantial ongoing obligations. Aircraft, fuel, employees, and airport operations require continuous financing, leaving financially weak carriers little room to absorb a sudden cash shortage.

- Thomas Cook's financial difficulties had been visible for months before its September 2019 collapse. Nevertheless, a potential buyout agreement at the end of August created expectations that the company might survive.

- Thomas Cook's likely failure became clear only during its final week. Despite worsening financial conditions and uncertainty over its rescue, the airline continued normal operations and ticket sales.

- Thomas Cook publicly confirmed normal operations just hours before shutting down. At 9:40 p.m. on September 22, 2019, the company responded to a customer on Twitter by stating that its flights and holiday operations were operating normally.

- Thomas Cook announced that it had ceased trading approximately five and a half hours after reassuring customers. In the early hours of September 23, the company published its final announcement, confirming that trading had stopped with immediate effect.

- Thomas Cook's public reassurance was accurate when issued, even though insolvency was imminent. Flights were still operating, customers were purchasing tickets, and ordinary activity continued while the company's financial future was being decided privately.

- Some Thomas Cook flights were boarding when the company officially ceased operations. Aircraft had been fueled, crews were on board, and passengers were preparing to depart. The insolvency announcement brought these activities to an immediate halt.

- The collapse instantly disrupted the commercial arrangements required to operate Thomas Cook flights. Crews were no longer employed by the operating company, fuel payments could not proceed normally, and aircraft ownership or leasing arrangements no longer supported continued operations.

- Passengers lose their normal rebooking arrangements when an airline collapses. Unlike an ordinary cancellation, an insolvent airline generally cannot arrange and finance alternative flights for affected customers.

- The United Kingdom's Civil Aviation Authority has a system for repatriating passengers following airline failures. The CAA can arrange seats on other airlines or organize replacement flights, effectively taking over essential passenger-return arrangements after a British carrier collapses.

- The CAA does not operate its own permanent fleet of repatriation aircraft. Instead, it maintains arrangements with airlines and charter operators that can provide aircraft when an emergency operation is required.

- Hi Fly, AtlasGlobal, and Wamos Air were among the charter operators identified as potential providers for CAA repatriation flights. These arrangements allow the authority to obtain aircraft capacity from operators in different parts of the world.

- A Malaysia Airlines Airbus A380 became one of the most unusual aircraft used in the Thomas Cook repatriation. Malaysia Airlines had A380 aircraft available for charter operations, allowing the CAA to secure an exceptionally large passenger aircraft.

- The Malaysia Airlines A380 flew empty from Kuala Lumpur to Manchester ahead of Thomas Cook's formal collapse. The aircraft was positioned after it became apparent that the airline was approaching insolvency.

- The A380 landed in Manchester shortly after midnight on September 23, 2019. It arrived only a few hours before Thomas Cook officially ceased trading, demonstrating that emergency replacement capacity was being organized while the airline was still operating.

- The CAA had begun preparing repatriation operations before Thomas Cook's final flights stopped. Other aircraft were also positioned in advance, enabling the authority to begin transporting stranded passengers on the same day as the collapse.

- Advance preparations allowed many Thomas Cook passengers to experience delays of only a few hours. Although the airline had suddenly disappeared, the rapid deployment of replacement aircraft prevented substantially longer disruptions for some travelers.

- The Malaysia Airlines A380 was assigned to return passengers from Palma de Mallorca. The Spanish holiday destination was particularly challenging because Thomas Cook had operated a large number of flights from Palma to numerous British airports.

- Thomas Cook served at least eight UK destinations from Palma de Mallorca. The transcript identified London, Cardiff, Birmingham, East Midlands, Manchester, Newcastle, Glasgow, and Belfast.

- Replacing Thomas Cook's Palma network with separate aircraft for every destination would have been difficult. The CAA instead concentrated passenger transportation onto a single, very large aircraft rather than attempting to source numerous smaller planes.

- The A380 operated approximately two-hour flights between Palma de Mallorca and Manchester. Manchester became the principal arrival point for passengers returning on this aircraft.

- Buses distributed returning passengers from Manchester to other British cities. The destinations mentioned were Glasgow, Newcastle, East Midlands, Birmingham, and London, allowing the CAA to serve multiple areas without operating separate flights to each one.

- One A380 could replace the passenger capacity of almost seven Thomas Cook Airbus A321 aircraft across its daily operations. The aircraft could complete up to three Palma–Manchester flights per day, providing combined capacity for nearly 1,500 passengers.

- The repatriation strategy prioritized aircraft availability and total passenger capacity over direct flights to original destinations. By combining one large aircraft with ground transportation, the CAA reduced the number of replacement planes needed.

- The Thomas Cook repatriation continued for several weeks. The prolonged operation required substantial charter-aircraft capacity to return passengers whose original journeys had been disrupted.

- The emergency created significant revenue opportunities for charter airlines. Aircraft operators received business from the replacement-flight program while the British government faced a substantial bill for organizing passenger returns.

- The expense of emergency repatriation was presented as preferable to leaving hundreds of thousands of passengers stranded internationally. The CAA's coordinated response demonstrated the value of having replacement-aircraft arrangements ready before a major airline failure.

- Five of the nine failed airlines examined had focused on low-cost, long-haul travel. Their concentration among the collapses pointed to problems with a model that had attracted investment and expansion but struggled to deliver sustainable profitability.

- Low-cost, long-haul aviation became more attractive through improvements in aircraft efficiency. Smaller, fuel-efficient aircraft capable of flying long distances created opportunities for airlines to offer cheaper intercontinental services.

- Low fuel prices were another essential foundation of the low-cost, long-haul model. Airlines could offer significantly cheaper fares when fuel expenses were relatively low, making expansion appear commercially attractive.

- The sharp decline in oil prices in 2014 encouraged rapid expansion by low-cost, long-haul airlines. Lower operating costs enabled these carriers to undercut established competitors and attract price-sensitive passengers.

- Long-haul budget airlines expanded their market share partly by charging substantially less than established carriers. This strategy was effective at attracting customers but left airlines vulnerable when the cost of operating long-distance flights increased.

- Sustained profitability in low-cost, long-haul aviation was described as rare outside Asia and Australia. The video identified AirAsia X, Scoot, and Jetstar as the principal examples of airlines that had achieved longer-term financial success with the model.

- Fuel prices began rising again in 2017, weakening the economics of budget long-haul operations. Airlines that had expanded while fuel was cheap faced increasing costs without necessarily having the ability to raise fares.

- Low-cost, long-haul airlines faced a difficult choice when fuel became more expensive. Raising ticket prices risked losing the market share they had gained, while maintaining low prices meant accepting worsening financial performance.

- Many low-cost carriers chose to protect market share rather than increase ticket prices. According to the video, this allowed their financial losses or distance from profitability to grow as fuel costs increased.

- Rising fuel expenses contributed to the failure of several long-haul budget airlines. The combination of low fares, thin margins, and increasing operating costs made previously aggressive expansion strategies difficult to sustain.

- Industry-wide prosperity helped financially weaker airlines remain in business longer than they otherwise might have. Strong passenger demand and favorable commercial conditions allowed companies with fragile business models to continue operating and expanding.

- Overcapacity was identified by analysts as another contributing factor in the wave of airline collapses. Airlines had increased the number of available seats and aircraft beyond what some markets could profitably support throughout the year.

- Years of airline profitability encouraged carriers to purchase aircraft aggressively. The industry had become accustomed to expanding capacity as a way to increase revenue and profits.

- Investors also contributed to excess capacity by financing airline growth. Access to investment encouraged additional expansion, even in markets where demand might not support the extra aircraft economically.

- The industry appeared to have reached the limit of the assumption that adding aircraft automatically increases profits. More capacity could still attract passengers, but additional operating expenses could outweigh the revenue generated.

- European airlines face a particularly costly problem when expanding fleets for peak summer demand. An aircraft might operate profitably when holiday travel is at its busiest but still require financing and other expenditure throughout the much quieter winter.

- Aircraft that sit unused during winter can turn successful summer expansion into an annual financial burden. Airlines must account for the full year's ownership, leasing, and operating costs rather than judging additional aircraft solely by summer demand.

- Seasonal cash shortages, rising fuel prices, and excess capacity reinforced one another. Airlines that expanded aggressively during favorable conditions could face higher costs, weaker margins, and sharply reduced cash receipts at the same time.

- The video predicted that further prominent European airline collapses would occur in September or October. The narrator argued that increasingly difficult operating conditions, combined with the annual decline in summer-related cash flow, would continue to threaten financially weak carriers. This was a prediction made at the time, not an established outcome for subsequent years.
