Hi...

No ILAM and Jain University are not tied up.

I would say that both are good , but ILAM would be the best.

ILAM is the reputed college.It has its campus even in Mumbai, Ahmedabad , Jaipur, Delhi , Dehradun which are 15 years old colleges.You can get various opprtunities, insights and knowledge studying in the ccollege.

ILAM is best known for the internships which are provided to the students which gives them the real time experience.Aviation is one of the growing fields and has a good scope in future.The course curriculum is designed to provide the students with the specialised knowledge and training in the field of aviation.

Coming to the Jain University is also a good college for the International Business and Airport and Aviation Management.
They tailor the students in such a  way they are innovative and had got full knowledge in their subjects. They are also given with projects.The curriculum is based on the research, interaction and consultation with the aircraft industries.It provides various career options for the students.

Overall both the colleges are good for the aviation management

Best luck
