ANALYSIS: Why September is ‘collapse season’ in the aviation business

Collapse season. The phrase sends a shudder through everyone involved in travel and aviation. September is historically known as the “collapse season” for the travel and aviation industries.

As the busy summer peak ends, cash inflows from holiday bookings dry up, but massive bills for aircraft maintenance, fuel, and hotel commitments come due, exposing companies heavily burdened by debt.

The structural mismatch between seasonal revenue and fixed costs creates a recurring vulnerability that has claimed operators of every size across decades. Cash collected during the high-volume summer months is often already committed to suppliers and lessors, leaving balance sheets exposed once the booking curve flattens. Fuel price volatility, currency swings and competitive pressure from online platforms intensify the squeeze at precisely the moment when liquidity is weakest.

TC’s Goose Cooked

Thomas Cook Group illustrated the scale of risk on 23 September 2019. The 178-year-old operator, which maintained a fleet of 94 aircraft together with hotels and high-street shops, entered compulsory liquidation after lenders declined a final request for approximately €230m in emergency funding.

The group carried a debt burden reported at around €2.2bn on its balance sheet, part of total liabilities that later assessments placed near €10.5bn when intercompany obligations were included. The failure triggered Operation Matterhorn, the largest peacetime repatriation organised by England Civil Aviation Authority. Dozens of temporary aircraft were chartered to return 150,000 British travellers, while roughly 600,000 customers worldwide saw holidays disrupted or cancelled.

Thomas Cook had pulled out of Dublin the previous Januar an early sign that things were going awry. The episode confirmed how rapidly a once-dominant vertically integrated model could unravel when summer cash flows proved insufficient to service legacy debt and modern digital competition.

XL and other exits

The same four-week window in September 2019 claimed additional European carriers. XL Airways France ceased operations on 30 September after efforts to find a rescue buyer failed.

The long-haul budget airline, which specialised in routes to the Caribbean and the United States, could not withstand low-cost competition and the abrupt withdrawal of investor support. Adria Airways, the national carrier of Slovenia with 58 years of history, filed for bankruptcy on the same date and cancelled all scheduled flights. Aigle Azur, France’s second-largest airline at the time, had already grounded its fleet on 2 September, stranding 19,000 passengers when high-profile backing evaporated.

These successive failures compressed market confidence and demonstrated that even mid-sized operators with established networks remained exposed once the summer revenue peak passed.

Earlier September collapses followed comparable patterns. XL Leisure Group and XL Airways England entered insolvency on 12 September 2008 under the combined weight of a global economic downturn and elevated aviation fuel costs.

England’s third-largest package holiday group left 90,000 holidaymakers stranded and forced the cancellation of 200,000 forward bookings. Court Line Aviation, operating through its Clarksons Holidays brand, experienced the full commercial fallout in early September 1974 after an August grounding.

The pioneer of low-cost Mediterranean packages left approximately 100,000 customers stranded or out of pocket, prompting subsequent regulatory reforms in England. Ansett Australia placed its operations into administration on 13 September 2001, an event accelerated by the immediate industry shock of the attacks two days earlier but rooted in pre-existing systemic distress.

SAS survived. SAS Scandinavian Airlines faced make-or-break restructuring deadlines in September 2023 under Chapter 11 protection. Years of pandemic losses and industrial action had left the carrier dependent on a capital overhaul that ultimately removed it from public listings and placed ownership partly with Air France-KLM. In the United States, iAero Airways and Western Global Airlines simultaneously confronted critical September 2023 bankruptcy deadlines under post-pandemic debt loads. iAero, a major charter operator, eventually ceased all operations.

Each case revealed the same underlying dynamic: summer receipts that proved temporary against permanent cost structures.

When Budget went bust

Ireland has experienced its own sequence of failures, though the largest by employment impact occurred outside the strict September window. Budget Travel, then the country’s largest tour operator, ceased trading on 25 November 2009 and entered provisional liquidation.

The sudden closure eliminated 172 jobs and shut 17 retail shops nationwide, including branches in Athlone and Mullingar. Approximately 747 holidaymakers were left stranded abroad and hundreds more saw forthcoming trips cancelled. Plunging consumer demand during the recession combined with heavy pre-booked contract penalties and a licensing dispute with the Commission for Aviation Regulation to produce the outcome. Club Travel later acquired the brand name.

Fáilte Travel, also known as Gerry McMahon Travel, collapsed in August 2008. The High Court appointed a liquidator after consumer claims exceeded the firm’s bond by more than €1.5m. Around 250 tourists were stranded in Cyprus alone, with further groups affected elsewhere.

The operator had been cutting margins and offering free accommodation incentives while switching air carriers shortly before failure. The Aviation regulator arranged repatriation for those already abroad and refunds for those yet to travel, yet the practical difficulty of securing alternative arrangements remained for many customers. The draw on the bonding system reached €1.6m.

Shock of summer 2016

Lowcostholidays ceased trading on 15 July 2016 when its parent, Lowcost Travelgroup, entered administration. Roughly 140,000 customers were affected globally, including 27,000 already in resorts and 110,000 with future bookings. In Ireland, 4,200 customers submitted claims totalling €3.8m.

The firm had been bonded for only €79,243. Administrators cited market headwinds, intense competition and the fall in sterling after the Brexit referendum. Payments to hotels had not been forwarded in many cases, leaving customers with unpaid bills. The shortfall required a substantial draw on the Travellers’ Protection Fund, consuming an estimated 75pc of its resources at the time and costing the Irish bonding system approximately €3.5m. Industry representatives, including Cormac Meehan of the Irish Travel Agents Association, called for an immediate review of bonding arrangements, noting that some operators active in the Irish market were not bonded with the Commission for Aviation Regulation at all.

December default

More recently, Dublin-based Platinum Travel ceased trading on 19 December 2024. Owned by Ciara Foley and directed by Austin Carroll, the agency left around 85 customers with disrupted bookings. Compensation claims submitted through the Irish Aviation Authority reached approximately €444,412. The firm’s bond covered only a fraction of that total, requiring further recourse to the Travellers’ Protection Fund and an application for additional support from the Department of Transport.

Irish consumer protection for outbound travel rests primarily on the Package Holidays and Travel Trade Act 1995, which superseded earlier measures in the Transport (Tour Operators and Travel Agents) Act 1982. Both statutes responded to high-profile failures such as Bray Travel in 1980 and Carousel in 1984. The framework established a bonding requirement of 4pc of turnover for tour operators and 10pc for travel agents, intended to finance repatriation and refunds. A Travellers’ Protection Fund was created to cover shortfalls once individual bonds were exhausted. Contributions to the fund were suspended in 1987 once reserve targets appeared to have been met.

Outdated protections

The formal travel industry once accounted for roughly 80pc of the market. It now represents 15 to 20pc. The bonding obligation continues to apply to that shrinking segment, effectively requiring it to underwrite protection for a far wider range of travel purchases, including those made through unbonded online platforms, bed banks and dynamic packaging.

Scheduled airline failures fall outside the scheme, as demonstrated by successive collapses of carriers such as Sabena, Swissair, Malev, Skynet, Eirjet, XL, FlyGlobespan, Air Berlin and Flybe. Cross-border bookings and changes in merchant-service practices have further complicated coverage. Critics argue that the system privatises risk for a minority of operators while leaving large volumes of consumer expenditure exposed.

Successive draws have depleted the Travellers’ Protection Fund. Fáilte Travel absorbed €1.6m in 2008. Lowcostholidays required €3.5m in 2016. By later assessments the residual balance had fallen to levels the Commission for Aviation Regulation itself regarded as inadequate. Additional Department of Transport transfers have been necessary in recent years to meet claims arising from smaller agency failures, including Platinum Travel. The fund’s structure, designed in an era of predominantly packaged holidays and high-street agencies, has struggled to adapt to a market dominated by low-cost airlines and online intermediaries.

Winter woes

Summer bookings generate the bulk of annual receipts, yet aircraft leases, hotel contracts, fuel hedges and staff costs continue through the quieter months. Operators that expand aggressively during peak periods or that carry high fixed debt find themselves unable to refinance or to meet supplier obligations once the revenue curve declines.

Online competition has compressed margins, while fuel and currency volatility can erase residual profitability within a single season. Regulatory bonding, although necessary for consumer protection, ties up working capital that might otherwise provide a liquidity buffer.

Over the years, proposals for reform have included a broader levy on all air travel to finance a more comprehensive protection scheme, covering scheduled airline failures as well as traditional package operators. Industry bodies have advocated collective bonding arrangements that would distribute risk more evenly across the remaining licensed sector.

Then a new complication, opening up competition internationally. An agency operating in an Easter European country has a different structure and different licensing requirements, but can now trade across borders. While the online agencies such as Loveholidays and Onthebeach which have enjoyed easy access to the Irish market, in the case of Loveholidays coming to dominate it in a short space of time, are bonded here, the consumer is completed unaware where the agency they are using is headquartered and whether they are covered by any protections. Increased regulation and requirements of the Eurppean package holiday directive have increased the burden on the formal trade without releasing any perceptible consumer protections.

Need for balance

Travel agents have long argued that any redesign must balance the need for consumer repatriation against the competitive disadvantage imposed on bonded firms relative to unregulated platforms. The historical record of September and autumn collapses demonstrates that the underlying seasonal mismatch has not disappeared. Cash continues to flow in during the summer and out thereafter, leaving leveraged operators vulnerable at the same point on the calendar year after year.

The pattern is therefore structural rather than accidental. Each high-profile failure, whether Thomas Cook on a global scale or Budget Travel and Lowcostholidays within the Irish market, has exposed the same combination of seasonal revenue dependence, fixed cost rigidity and inadequate liquidity reserves.

Regulatory frameworks designed for an earlier market structure have been repeatedly tested and found insufficient to prevent either the collapses themselves or the subsequent strain on protection funds. As long as the industry retains this cash-flow asymmetry, the months following the summer peak will continue to reveal the financial weaknesses that peak-season activity temporarily conceals.

Collapsing month: Tour Operators & Leisure Giants

Thomas Cook Group (September 23, 2019): The world’s oldest travel agency (178 years) collapsed under a £1.9 billion debt burden. Its liquidation triggered “Operation Matterhorn,” the UK’s largest peacetime repatriation, rescuing 150,000 stranded British travellers and affecting 600,000 tourists worldwide.
XL Leisure Group / XL Airways UK (September 12, 2008): The UK’s third-largest package holiday group collapsed due to the global economic downturn and high fuel costs, stranding 90,000 holidaymakers and cancelling 200,000 forward bookings.
Court Line Aviation (August/September 1974): A pioneer of cheap Mediterranean package holidays (Clarksons Holidays), its collapse left 100,000 holidaymakers stranded and reshaped UK travel regulations.

Major Airline Bankruptcies & Failures

The “Gloom of 2019” Wave (September 2019): Four airlines collapsed within a four-week span:
XL Airways (September 30, 2019): French long-haul budget airline that ceased operations after failing to secure a buyer.
Adria Airways (September 30, 2019): The 58-year-old national carrier of Slovenia filed for bankruptcy.
Aigle Azur (September 2, 2019): France’s second-largest airline filed for bankruptcy, grounding its fleet and stranding 19,000 passengers.
SAS – Scandinavian Airlines (September 2023): Faced critical restructuring deadlines in September 2023, leading to a massive equity overhaul and delisting from stock exchanges.
iAero Airways & Western Global Airlines (September 2023): Two major US aviation companies (charter and cargo) buckled under post-pandemic debts, with iAero ceasing all operations.
Ansett Australia (September 13, 2001): Australia’s second-largest domestic airline collapsed, exacerbated by the immediate shockwaves of the September 11 attacks.

Famous Irish collapses (from all months):

Bray Travel (1980): A high-profile collapse that led to the creation of the Transport (Tour Operators and Travel Agents) Act, 1982.
Carousel (1984): Another high-profile collapse that influenced the Package Holidays and Travel Trade Act, 1995.
Fáilte Travel (August 2008): The tour operator collapsed, leaving hundreds stranded (including around 250 in Cyprus). The total consumer claims exceeded the company’s bond by over €1.5 million, leading to a draw of €1.6 million on the bonding system.
Budget Travel (November 25, 2009): Ireland’s largest tour operator at the time, it collapsed resulting in 172 job losses, the closure of 17 retail shops, and leaving 747 holidaymakers stranded abroad. The cause was plunging demand during the recession and unsustainable losses.
Lowcostholidays / Lowcost Travelgroup (July 15, 2016): The online travel agency collapsed, affecting 27,000 people already on holiday and 110,000 future bookings. The company was bonded in Ireland for just €79,243, but claims from Irish customers totalled €3.8 million, depleting 75% of the Travellers’ Protection Fund.
Platinum Travel (December 19, 2024): A Dublin-based travel agency that ceased trading, affecting around 85 customers. Compensation claims submitted via the Irish Aviation Authority (IAA) reached approximately €444,412.
