Jet Delivery Delays Threaten Airline Expansion Amid Soaring Demand Airlines are poised to generate over $40 billion in profits this year, supported by low fuel prices and strong economic growth, according to a recent analysis by Irish aircraft lessor Avolon. However, the industry faces significant challenges as unprecedented backlogs in new aircraft deliveries threaten to impede expansion plans well into 2026. Production Backlogs and Market Impact Avolon, one of the world’s leading aircraft leasing companies, reports that order backlogs at major manufacturers Airbus and Boeing now extend beyond 11 years based on current production rates. This prolonged delay complicates strategic growth initiatives for airlines, which may be compelled to continue operating older, less fuel-efficient jets or scale back their expansion ambitions. The shortage of new aircraft is already influencing the market; Ryanair recently warned that European travelers could face airfare increases of 3 to 4 percent this year due to constrained capacity driving up prices. In response to these backlogs, both Boeing and Airbus have increased production. Boeing raised its deliveries by 75 percent last year, while Airbus achieved a more modest 3.5 percent increase. Despite these efforts, the gap between orders and deliveries remains substantial, prompting airlines to adjust their strategies. For instance, Delta Air Lines is focusing on more profitable segments such as premium cabins, utilizing new aircraft like the Boeing 787 Dreamliner to attract higher-yield customers. Industry Adjustments and Regional Developments The delivery delays are prompting widespread adjustments across the industry. Airlines are revising profit forecasts and expansion plans amid heightened competition and geopolitical uncertainties. Korean Air has cautioned that these factors could complicate airline strategies in 2026. Meanwhile, consolidation continues in Europe, with Air France-KLM tripling its stake in Scandinavian carrier SAS to 60.5 percent, and Lufthansa planning to increase its holding in Italy’s ITA from 41 percent to 90 percent. Low-cost carriers, led by Ryanair—which is scheduled to receive 29 new Boeing jets this year—remain at the forefront of growth in the region. Avolon projects that manufacturers will deliver $120 billion worth of new aircraft in 2024, representing a 20 percent increase over 2023. Leasing companies, including Avolon and its Irish peers Aercap and SMBC Aviation Capital, are expected to finance approximately half of these deliveries. The leasing model, whereby companies purchase aircraft and lease them to airlines, continues to be a cornerstone of the industry, offering airlines flexibility amid delivery uncertainties. Dublin, a global hub for aircraft leasing, will host the upcoming Airline Economics conference, which will convene industry leaders to address these challenges. Jim Morrison, Avolon’s chief risk officer, highlighted emerging growth regions such as India, the United Arab Emirates, and Saudi Arabia, noting that “airline financial performance continues to strengthen, with the industry expected to record its fourth consecutive year of profitability.” Despite robust profits, the persistent delays in jet deliveries may constrain the industry’s ability to fully capitalize on surging demand, compelling airlines to reconsider their growth strategies in an increasingly complex market.

Can Retired Military Aircraft Power U.S. Data Centers? In the arid expanse of the Arizona desert, thousands of retired military aircraft lie dormant in orderly rows at the Aerospace Maintenance and Regeneration Group, commonly known as the “Boneyard,” located at Davis-Monthan Air Force Base. For decades, this facility has symbolized the final chapter for American airpower. However, a recent analysis by the U.S. Energy Information Administration (EIA) proposes a novel possibility: these decommissioned aircraft engines could be repurposed to help power the nation’s rapidly expanding data centers. Rising Electricity Demand and Emerging Solutions The EIA’s latest *Today in Energy* briefing highlights that engines from retired U.S. military aircraft could theoretically generate up to 40,000 megawatts (MW) of electricity—surpassing Arizona’s current total capacity by approximately 10%. Although this figure remains theoretical, it underscores a significant potential resource as the United States confronts soaring electricity demand, particularly driven by data centers supporting artificial intelligence and cloud computing technologies. Utilities nationwide are struggling to accommodate the explosive growth of data centers. In many regions, developers face prolonged delays in securing grid connections. Conventional approaches, such as constructing new power plants or expanding grid infrastructure, are often slow and expensive. Market responses reflect this challenge: 65% of contractors anticipate continued growth in data center construction, while major technology companies increasingly seek long-term electricity contracts to stabilize their power supply amid market volatility. In response, some energy developers have begun exploring unconventional power sources. In states like Texas, modified jet engines—originally designed for aircraft—are being adapted as stationary generators, each capable of producing approximately 48 MW, sufficient to power a small town or a large data center. This emerging trend raises the question of whether the extensive inventory of retired military engines at the Boneyard could serve as a substantial, untapped energy reserve. The Boneyard’s Engine Inventory As of March 2025, Davis-Monthan Air Force Base houses roughly 4,000 retired military aircraft encompassing multiple generations and mission profiles. These aircraft are equipped with four primary types of turbine engines: turbojets, turbofans, turboshafts, and turboprops. The EIA’s analysis excludes older turbojets due to their low efficiency and afterburning turbofans because they are unsuitable for stationary power generation. Despite these exclusions, the remaining engines still represent considerable potential. Turbofan engines, in particular, are notable for their capacity. The EIA estimates that these engines alone could collectively provide around 32,000 MW of electricity. This is significant given that turbofan technology forms the basis of aeroderivative gas turbines, a well-established technology widely used in stationary power generation. Challenges and Market Dynamics Repurposing military aircraft engines for electricity generation presents several challenges. The conversion process is complex and costly, especially when compared to other alternatives such as recycling nuclear reactors from decommissioned Nimitz-class supercarriers, which themselves face substantial technical and regulatory obstacles. Additionally, community opposition and regulatory scrutiny frequently hinder new data center projects, often delaying or preventing their development. In light of the growing demand for electricity, the U.S. government has instructed PJM Interconnection—the nation’s largest grid operator—to conduct auctions that allow technology companies to bid on new electricity generation capacity. This initiative reflects the urgency to secure reliable power sources as data center expansion accelerates. While the concept of powering America’s digital infrastructure with engines from its military past remains largely theoretical, the intensifying search for innovative energy solutions is prompting a reevaluation of even the most unconventional resources. As the nation’s electricity needs continue to grow, retired military aircraft engines may yet find a surprising new role in the country’s energy landscape.

Fraport AG Implements Certified AI Security at Frankfurt Airport Fraport AG has introduced a certified artificial intelligence (AI) security system at Frankfurt Airport, representing a significant advancement in airport screening technology. The newly deployed software, known as APIDS (Automatic Prohibited Item Detection Systems), is now operational across more than 50 Smiths Detection CT scanners throughout all terminals. This system identifies potentially hazardous items in carry-on luggage, thereby streamlining the decision-making process for security personnel. Pioneering AI-Assisted Screening in Europe Frankfurt Airport distinguishes itself as the first European airport to implement AI-assisted screening on such a large scale with full regulatory certification. Unlike ongoing AI trials at Amsterdam Schiphol or the CT-focused upgrades at London Heathrow and Gatwick, Frankfurt’s approach emphasizes national regulatory approval achieved through close collaboration and rigorous testing with authorities. This ensures that while the AI system highlights suspicious objects, the ultimate decision-making authority remains with human officers. Operational Mechanism and Benefits During routine operations, such as a busy Monday morning, trays pass through CT scanners that generate detailed 3D images of luggage contents. APIDS analyzes these scans in real time, detecting dense or unusual shapes—such as a charger entangled with a metal water bottle—and marking them with a red outline on the screen. This visual cue serves as an alert rather than a definitive judgment. Security officers can then examine the flagged area in greater detail by rotating and zooming the image, enabling them to quickly determine whether a secondary inspection is warranted. This process results in faster passenger throughput and reduces staff fatigue by minimizing the frequency of exhaustive manual searches. Operational Gains and Emerging Challenges The deployment of certified AI at Frankfurt Airport has yielded clear operational advantages, including enhanced efficiency, more consistent screening outcomes, and improved passenger flow. However, the integration of AI also presents new challenges. The potential for false alarms and automation bias persists, and regulatory constraints may limit operational flexibility. Security personnel must adapt to revised workflows and receive additional training to effectively collaborate with AI systems. Beyond immediate operational concerns, the adoption of AI-driven security introduces broader enterprise risks. As organizations like Fraport increasingly utilize generative AI tools, they face heightened security threats, the need for continuous security posture management, and the imperative to prevent unauthorized AI usage that could compromise compliance, intellectual property, or reputation. The industry is responding with intensified scrutiny of AI data handling practices and demands for robust certification and attestations. This environment is likely to accelerate AI security investments among competitors, fostering further innovation and funding within the sector. Contextualizing AI Security Across European Airports Frankfurt’s certified AI-assisted screening sets a new benchmark in Europe. In contrast, Amsterdam Schiphol is currently engaged in AI trials and partnerships, such as Project DARTMOUTH, positioning AI as a collaborative tool rather than a fully certified solution. Meanwhile, London Heathrow and Gatwick focus on modernizing CT technology to enhance passenger convenience, allowing liquids and electronics to remain in bags, with an emphasis on speed and comfort. While UK airports highlight the benefits of advanced 3D scanners, Frankfurt’s approach is defined by the integration of certified AI systems that automatically detect prohibited items, thereby establishing a new standard for security operations. As AI becomes increasingly embedded in airport security frameworks, the interplay between technological innovation, regulatory compliance, and operational risk will continue to be a critical area of focus.
