The overseas departure graphical front end is specially developed for aviation companies carrying out overseas ground passenger services. In addition to traditional functions such as check-in and boarding, the overseas departure graphical front end supports multiple languages and thus meets the needs of local ground agents. Because of its graphical interface and common way of organizing work flow, this front end is easy for training and conducive to cutting the training costs of overseas ground agents. Moreover, maintenance of this front end is easy due to its compatibility with major host platforms like SIT CUTE and ARINC iMUSE. Those features have ensured TravelSky’s expansion of international business and enhanced aviation companies’ integration of data and service.
