Abstract
The limited nature of oil, and hence aviation fuel is increasingly becoming a restraining factor for the air transport industry. Also, fuel efficiency is crucial for commercial air transport as fuel is one of the most costly operating parameters for an airline. This study employs structural equation modelling (SEM) approach to identify key dimensions influencing fuel efficiency in air transport (FEAT) and to explore the correlational relationships among constructs from the perspectives of fuel efficiency improvement. Self-administered questionnaires were used to collect data from 375 aviation experts. Correlation, multi-group moderation analysis, and interaction using structural equation model were used to analyses these data. The results and applications of SEM evolve a variety of findings; aircraft technology & design, aviation operations infrastructure, socioeconomic & political measures, and alternative fuels & fuel properties, and aviation infrastructure are proved to be the five key influential dimensions affecting the fuel efficiency and have a positive effect on the FEAT. In addition, the moderating effect of industry type and experience were established. The results also showed that no significant interaction effect between dimensions of FEAT. The findings of this research can provide air transport valuable information for designing appropriate strategy for fuel efficiency improvement.

The limited nature of oil, and aviation fuel is increasingly becoming a restraining factor for the air transport industry
Li et al [53] employed the virtual frontier dynamic range adjusted measure to estimate the energy efficiency of 22 airlines during the period of 2008–2012, and the results showed that the aggregate airline energy efficiency consistently increased from 2008 to 2012
We argue that when socioeconomic & policy measures (SEP) measures are low, there will be positive relationship between aircraft technology & design (ATD) and alternative fuels & their properties (AFP) for fuel efficiency in air transport (FEAT)
Summary
The limited nature of oil, and aviation fuel is increasingly becoming a restraining factor for the air transport industry. Methodology This study employs structural equation modelling (SEM) approach to identify key dimensions influencing fuel efficiency in air transport (FEAT) and to explore the correlational relationships among constructs from the perspectives of fuel efficiency improvement. The mean price of jet fuel has increased over the previous 10 years, which was above $120 a barrel [36, 53]. The growing demand of jet fuel and high price will force air transport to improve fuel efficiency. The International Air Transport Association (IATA) seeks to raise fuel efficiency across the air transport industry by 1.5 % per annum up to 2020 [37], while the International Civil Aviation Organization (ICAO) is attempting for a 2 % per
