Hey! 

IIFT currently have only two campuses, Delhi and Kolkata. The one in Andhra Pradesh hasn't open up yet. The sole difference between the two campuses are that the top 160 get admission in IIFT, Delhi and the next get 150 admission in Kolkata. Secondly the number of years of construction, IIFT, Kolkata is hardly ten years old. So, few business competitions won't be open up for them. Rest curriculum and everything is same.   

Hey.....

Well again it's a personal choice but the priority for majority of students has been IIFT Delhi then IITF Kolkata and then the last one. The one reason may be that the Delhi campus is 43 year older than one in Kolkata. Else all the things are same in all three IIFT
