Which is the best college in Kerala to pursue BBA in logistics, aviation or tourism?

Logistics is not offered as a specialisation in BBA and MBA. There are institutes which offer BBA in aviation. You may check with Frankfinn: Frankfinn Institute of Air Hostess Training, Thiruvananthapuram Thiruvananthapuram, Kerala. Frankfinn Institute of Air Hostess Training, Thrissur Thrissur,

I think, you can contact a flying club as they can give you the clear idea about aviation study.
