Specifically, the goal was to understand how <em>causal illusions</em> interact with perceptual biases with and without irrational reasoning. A total of 408 airline pilots participated in an experiment using Airbus® aircraft TCAS/ROSE simulators. Analyses were conducted using <em>structural equation modeling</em> (SEM), controlling for the effects of fatigue and flight hours. Results indicated that causal illusions were 82.4% predictive of UAP sightings only when magical inference was present. Our experimental evidence shows that UAPs may be explained as cognitive biases and would pose a threat to aviation safety if pilots—or even aircraft AIs—were to detect them in an irrational way (e.g., as alien objects). A novel theorization that integrates major perception, clinical, and cognition models is offered. Additionally, the authors discuss the implications for aviation safety and determine when a UAP sighting may pose a real danger on a commercial flight.</p></div>","PeriodicalId":14925,"journal":{"name":"Journal of Air Transport Management","volume":"119 ","pages":"Article 102617"},"PeriodicalIF":6.0,"publicationDate":"2024-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141291451","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}

Does this translate to enhanced commercial revenue, and if so which revenue types—food and beverage, retail, and other terminal services—are impacted? Leveraging a unique panel data of passenger dwell time at 89 U.S. airports, this study explores its influence on non-aeronautical revenues. We find that dwell time positively influences non-aeronautical revenues (10% increase in dwell time implies a 5% increase in revenues) with varying impacts on the revenue components. Specifically, we find that a 10% increase in dwell time is associated with an increase of 8% and 6%, respectively, in food and beverage as well as retail revenues, but with no significant impact on other terminal services revenues. Importantly, these impacts further vary with the airport terminal design, which we categorize as either linear, finger pier, or concourse. Our findings suggest that non-aeronautical revenues increase in dwell time at both linear and finger pier airports, with no such impact at concourse airports. Further, dwell time elasticities for food and beverage are roughly double at linear-design airports than at finger pier design airports. These are instrumental insights for further airport development and of merit for the discourse on airport privatization and regulation.</p></div>","PeriodicalId":14925,"journal":{"name":"Journal of Air Transport Management","volume":"118 ","pages":"Article 102620"},"PeriodicalIF":6.0,"publicationDate":"2024-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0969699724000851/pdfft?md5=1df747b1cd61227b221552459d01c4a1&pid=1-s2.0-S0969699724000851-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141249727","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 paper, we present a simple model of optimal promised performance. We then apply this model to the airline industry, and we develop hypotheses for how changes in market conditions -- the availability of on-time performance data, competition, and prevalence of connecting passengers -- lead to changes in promised performance via their impact on one or both components of the aforementioned promise tradeoff. Lastly, we test our hypotheses using airlines on-time performance data. Our results provide support for our hypotheses, and more broadly for our model of promises and the associated tradeoffs, indicating that airlines promise more when the cost of failing to attain the promised performance level is low: When passengers are less informed about airlines' on-time performance; when airlines face little competition; and, when there are relatively fewer connecting passengers.</p></div>","PeriodicalId":14925,"journal":{"name":"Journal of Air Transport Management","volume":"118 ","pages":"Article 102618"},"PeriodicalIF":6.0,"publicationDate":"2024-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141249725","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}

It collected 39,616 comments from thirteen smart airports, and 25,572 tweets were analyzed. Most mentioned words about the smart airport included \"technology\" and \"security\". Comments also highlighted concerns about airport customer service, including \"bag,\" \"transit,\" and \"disabled.\" The results also reveal that travelers are more concerned about the outcome of these facilities, such as the efficiency and time management of flights via smart facilities. The most mentioned words in the tweets related to smart airport operations are \"flight,\" \"waiting,\" and \"time\". Despite most smart facilities being equipped in the airports aiming to raise travelers' satisfaction, the results showed that 12 smart airports' tweets were generally neutral. Smart airport facilities might not add as much value to the airport impression as we expect. Brisbane International Airport was the only one with a positive perception of smart airport facilities. Most travelers mentioned that the airport had faster and better wifi and the airport is continuously improving. In contrast, Charles de Gaulle Airport and London Heathrow Airport had the highest percentage of negative sentiment, with 25.90% and 27.52% of tweets being negative, respectively. Travelers' complained that self-check-in kiosks were a mess, unhelpful staff and poor wifi. The results reveal travelers' concerns regarding smart airport facilities, and they let us know the importance of smart facility management. Smart airport facilities were initially designed to shorten travelers' time and enhance satisfaction, yet unhelpful staff and poor managed kiosks raise dissatisfaction. This study helps airport managers and operators to address the weakest part of smart airports as reflected in social media comments. It also fills the academic voids in examining travelers' satisfaction with smart facilities using social media and sentiment analysis via artificial intelligence.</p></div>","PeriodicalId":14925,"journal":{"name":"Journal of Air Transport Management","volume":"118 ","pages":"Article 102600"},"PeriodicalIF":6.0,"publicationDate":"2024-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141241428","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}

As crucial stakeholders, urban residents have a growing demand for goods delivery, and they are in the process of understanding this new technology. Understanding their acceptance and quantifying their preferences can effectively promote the development of UAV delivery systems. While scholars have conducted extensive research on this topic, there remains a lack of detailed analysis regarding consumer heterogeneity and specific service experiences, especially in China, which is one of the largest potential markets for urban air mobility and UAV applications. This study addresses pertinent questions, including in high-density urban areas, the potential user characteristics of UAVs for instant delivery, the types of goods users prefer UAVs to transport, and how users prefer goods to be handed over to them. Conducted in Chengdu, a major city in southwest China, the survey collected 2,008 validated responses, encompassing potential users of urban air delivery. Employing a discrete choice model (DCM) for quantitative analysis, market share and willingness to pay were derived based on field data, with the identified issues designed as attribute variables integrated into the model. The findings reveal that under suitable services, the UAV market share can reach 21.2%, while electric bike and car deliveries persist as the mainstream in on-demand delivery, constituting 51.8% and 27.0%, respectively. Notably, consumers’ choices are significantly influenced by their socioeconomic status and key indicators. As the cost of UAVs increases relative to electric bike and car deliveries, respondents tend to prefer the electric bike, indicating that UAVs are not the preferred substitute. However, when the price falls below 9.5 CNY, UAVs become more appealing than cars. The identification of five latent classes reflects distinctly different user attitudes towards delivery services in China. The analysis of key attribute elasticity guides adjustments in delivery efficiency and pricing, aligning with market conditions. These results elucidate the intriguing psychology of Chengdu consumers when embracing this new technology. For actively accepting consumers, the hope is for UAV delivery to offer a more convenient service experience, with customized services especially between the arrival of UAVs and pick-up emerging as a distinctive feature. We also discusses regional heterogeneity and implications of the pandemic. As an effective supplement to existing studies, we posit that when UAVs meet customer demands for affordability and high-quality service, they will emerge as the primary force in Chengdu’s future urban air market.</p></div>","PeriodicalId":14925,"journal":{"name":"Journal of Air Transport Management","volume":"118 ","pages":"Article 102613"},"PeriodicalIF":6.0,"publicationDate":"2024-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141241429","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}

In this regard, this study presents a novel auction-based airport slot reallocation scheme considering the grandfather rights of airlines, in which participating airlines are required to submit bids for individual slots. The scheme includes allocation, payment, and compensation rules that aim to attain maximum social welfare by allowing the removal of grandfather rights and providing appropriate compensation. Although the proposed scheme neglects the interdependent effects between slots to reduce model complexity, we show that it achieves economic effectiveness while inducing voluntary participation and truthfulness of airlines.

Intermodal Passenger Transport Service (IPTS), the most typical of which is the Air-Rail Integration Service (ARIS), is one new way to solve this problem. Although some service products have been derived, intermodal travel services are still in their infancy due to problems such as long transfer time and inconvenient connectivity arising from the fact that those products fail to take into account the complexity of transfers between multiple hubs, resulting in a low penetration rate of intermodal services. Therefore, this study constructs a universal Hybrid Choice Model (HCM) framework that includes mode choice and city choice based on an online stated preference (SP) survey about multi-hub intermodal transportation in the Beijing-Tianjin-Hebei urban agglomeration, and introduces travelers' concerns about travel security, comfort, convenience and reliability as attitudinal variables, which expands the research on IPTS. Then the willingness to pay (WTP) for travel service is evaluated to demonstrate intermodal travelers' preference for shorter transfer time, transferring in the metropolis, more reserve time for air than rail, and the impact mechanisms of luggage through-handling service and mutual recognition mechanism of security checks. Last but not least, through scenario testing, we find that the excessive concern for security and comfort among high-educated and high-income passengers with a low tolerance for transfer time will reduce the market share of air-rail.
