The cost of fuel and its availability are among the most major concerns for aircrafts and the aviation industry overall. Environmental difficulties with chemical pollutant emissions emitted by aviation machines are also connected to fuel consumption. As a result, it is crucial to examine factors that affect the overall fuel usage and consumption in the airport-based aviation industry. Several variables were investigated related to the total fuel consumed, such as dry operating weight (DOW) (KG), zero-fuel weight (ZFW), take-off weight (TOW), air distance (AIR DIST) (KM), and ground distance (GDN DIST). Analysis of the correlation between total fuel consumed as well as the extra fuel and selected variables was conducted. The results showed that the most positively associated factors with the total used fuel were the air distance (r2 = 0.86, p< 0.01), ground distance (r2 = 0.78, p< 0.01), TOW (r2 = 0.68, p< 0.01), and flight time (r2 = 0.68, p< 0.01). There was also a strong positive association between the average fuel flow (FF) and actual TOW (r2 = 0.74, p< 0.01) as well as ZFW (r2 = 0.61, p< 0.01). The generalized linear model (GLM) was utilized to assess the predictions of total energy usage after evaluating important outliers, stability of the homogeneity of variance, and the normalization of the parameter estimation. The results of multiple linear regression revealed that the most significant predictors of the total consumed fuel were the actual ZFW (p< 0.01), actual TOW (p< 0.01), and actual average FF (p< 0.05). The results interestingly confirmed that wind speed has some consequences and effects on arrival fuel usage. The result reflects that thermal and hydrodynamic economies impact on the flying fuel economy. The research has various implications for both scholars and practitioners of aviation industry.

Travel decisions during the COVID-19 pandemic might be substantially influenced by destination-based attributes, in particular, health safety measures at airports. In the current study, we aimed to assess the effects of the perceived importance of safety measures at the Sharm El Sheikh airport on the intention of international passengers to revisit the destination, which might reflect their behavioral control for traveling to other tourism destinations. A total of 954 international travelers were asked to fill out a survey to reveal their travel risk perceptions, the importance of airport safety measures, and their future intentions to revisit the destination, and the data were integrated in an SEM model. The results showed that passengers with low-risk perceptions and highly perceived importance of logistic and sanitization procedures, as well as traveler- and staff-related safety measures, were more likely to exhibit greater intentions to revisit the city and lower intentions to cancel or change future travel plans to other touristic regions. Health safety at airports should be stressed in future strategic plans by governmental authorities and stakeholder activities to mitigate the psychological barriers of tourists.

In this study, we aim to investigate environmental management representatives’ perceptions regarding the extent of the contribution of green hotel practices to achieving the environment-related sustainable development goals (SDGs). To achieve this aim, a questionnaire was developed and directed to the person in charge of environmental duties in the investigated hotels, who were selected by a convenience sample method. A sample of 48 participants from four and five Green Star hotels, representing 63% of the total Certified Green Star hotels in Egypt, was surveyed. The findings of the study revealed that the implementation of green hotel practices in the certified four and five Green Star hotels surveyed contributed positively to achieving SDG 6, SDG 12, SDG 7 and SDG 13, respectively. The main driver of the adoption of Green Star criteria was the hotels’ commitment to environmental sustainability. The findings also indicated that, overall, there were statistically significant differences between four and five Green Star hotels in all SDGs addressed. The main implication of this study is that hotel operators should properly incorporate green hotel practices into their operational plans to achieve the environment-related SDGs.
