This is particularly the case for (1) network planning and (2) maintenance planning. Despite the close interaction of these two departments, airlines typically evaluate plans from both domains separately. However, an integrated perspective is necessary to develop robust plans and effective recovery policies in this intrinsically uncertain environment. This paper presents a new modular, stochastic, discrete event simulation model of airline operations named ANEMOS (Airline Network and Maintenance Operations Simulation). ANEMOS contains both network and maintenance dynamics, allowing the evaluation of plans, policies, and scenarios from both domains. The model is validated using data from a major European airline. We show that the simulated results closely resemble the airline’s historical operational performance. ANEMOS is tested with a use-case investigating the effects of adding a second reserve aircraft to a fleet of fifty wide-body aircraft. The results show that the second reserve is capable of reducing cancellations by 55%. However, such does not cover the lost revenue associated with keeping an aircraft non-operational for a part of the time.</div></div>","PeriodicalId":14925,"journal":{"name":"Journal of Air Transport Management","volume":"125 ","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143776541","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this context, trajectory predictionwill be one of the most critical functions in future air traffic deconfliction services, and suitable algorithms will have to be implemented in both ground-based and airborne systems. These algorithms must be far more accurate, efficient and flexible than in present-day ATM. This study introduces a Long Short-Term Memory (LSTM)-based adjustable interpolation algorithm, which can be incorporated into future UAM decision support system architectures. In the absence of UAM operational data, the verification of the proposed algorithm focuses on a series of scenarios encompassing both airliner and helicopter flight trajectories. Results demonstrate that the proposed method reduces computation time by half without significantly sacrificing prediction accuracy compared to conventional linear interpolation methods. Furthermore, accuracy improvements of at least 50% are achieved compared to raw data, with no substantial increase in computational time. Additionally, the algorithm complexity is evaluated via big O notation analysis, showing that our proposed approach allows to train accurate prediction models efficiently even when a large amount of training iterations is required. With further developments, this algorithm shows high potential as the foundation trajectory prediction for UAM services in dense urban airspace, enhancing conflict detection and resolution capabilities and mitigating risks.</div></div>","PeriodicalId":14925,"journal":{"name":"Journal of Air Transport Management","volume":"125 ","pages":"Article 102777"},"PeriodicalIF":3.9,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143697663","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When the World Health Organization classified Covid-19 as a pandemic, in 2020, fuel prices fell drastically. However, as the global health crisis receded and governments abandoned mobility restrictions, demand for air travel progressively recovered. As a consequence, there was a rapid increase in prices. Additionally, in 2022, the conflict between Russia and Ukraine further intensified pressure on aviation fuel prices. Considering that fuel expenses constitute approximately one-third of airlines' cost structure, this study aims to analyze the relationship between aviation kerosene prices and domestic airfares in Brazil. The initial hypothesis suggests that, in an environment characterized by imperfect competition, the pass-through of prices between fuel costs and airfares occurs asymmetrically. Specifically, positive shocks in fuel prices would be quickly and fully reflected in airfare adjustments, while negative shocks would be delayed or have lesser impacts on airfares. However, results from a nonlinear autoregressive distributed lag (NARDL) model combined with the derivation of asymmetric cumulative multipliers do not support this hypothesis. Instead, evidence of symmetric pass-through was found, indicating that airfares respond symmetrically to fuel price shocks in the short term. Despite the dominance of only three companies in the domestic aviation market in Brazil, there are indications of fierce competition among airlines in the analyzed period. During periods of crisis, companies face difficulties in passing cost increases onto prices.</div></div>","PeriodicalId":14925,"journal":{"name":"Journal of Air Transport Management","volume":"125 ","pages":"Article 102785"},"PeriodicalIF":3.9,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143680516","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Whilst prior studies have evaluated between-group cultural differences, there remains a research gap on whether within-group subcultural differences challenge the assimilation of people into the safety culture of the wider group. Cultural differences in how causal factors are perceived in the context of systemic safety deficiencies can affect the implementation of safety management strategies. In the present study, pilots from airline-sponsored, self-funded, and ex-military initial training backgrounds were invited to categorise an identical set of aircraft accident causal factors using the Human Factors Analysis and Classification System (HFACS). Results from 121 participants found significant differences amongst the three groups in the attribution of human factors conditions to organisational-level and supervisory-level categories. Significant associations amongst HFACS categories also differed amongst the three professional groups, with a considerable number of same-level associations found between ‘Preconditions for Unsafe Acts’ at the same level. Familiarity with organizational cultures was considered to impact the perception of causal factors. The finding of same-level associations presents a new contribution to the theoretical basis of the HFACS taxonomy, calling for a conceptual change in the directionality of causal sequences. The results suggest that the direction of safety remedies for different parts of the organisation is dependent on perceived relevance, which differs amongst subcultural groups. Findings are relevant to industry, particularly international airlines with diverse employee subcultural groups, for the implementation of safety management systems.</div></div>","PeriodicalId":14925,"journal":{"name":"Journal of Air Transport Management","volume":"125 ","pages":"Article 102786"},"PeriodicalIF":3.9,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143680515","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During the 2010–2019 period, air travel increased by 35 %, less than a 49 % growth of cruise travel. Moreover, air traffic showed consistently higher seasonality than cruise traffic, as measured by Gini coefficients over our study period. To empirically investigate the facilitating and restraining factors affecting air travel to the Bahamas, we estimate a structural equation of passenger traffic and airfare, using panel data consisting of monthly air traffic from 96 countries to the Bahamas over the years from 2015 to 2023. Our results shed light on the important role played by flight frequency, direct flight service, low-cost carriers, and airport connectivity in lowering airfare and thus driving inbound air traffic to the Bahamas.
