It was necessary to study whether the use of Garuda electronic flight manual software and Garuda electronic airway manual could ease the duties of the Pilot on board the aircraft. This research aimed to know the influence of implementing the Garuda electronic flight manual and the Garuda electronic airway manual on flight safety by optimizing human resources. The study used the Path Analysis method. The samples of this research were 30 pilots as the users and processors of the Garuda electronic flight manual and the Garuda electronic airway manual. The study found that the variable of flight safety was directly influenced by the implementation of the Garuda electronic flight manual, the Garuda electronic airway manual, and the optimization of human resources.

This research aimed to know the direct and indirect influences of service quality and web check-in on the intention to reuse Garuda Indonesia Airline mediated by passenger trust at Soekarno-Hatta Airport. The research was quantitative, with the data collecting method using a questionnaire distributed online through a purposive sampling technique to 210 passengers of Garuda Indonesia Airline. The data was analyzed using the partial least squares-structural equation modeling (PLS-SEM) method. This research showed five direct influences: the influence of service quality and web check-in on passenger trust, the influence of service quality, web check-in, and passenger trust on the intention to reuse Garuda Indonesia Airline. Passenger trust could mediate the influence of service quality and web check-in on the intention to reuse Garuda Indonesia Airline at Soekarno-Hatta Airport. From the results of this research, it could be concluded that service quality and web check-in through passenger trust are needed to reach the intention of reusing Garuda Indonesia Airline.
