I thnk NGP can be a good option for setting up a cargo hub. Maybe Blue Dart etc can be placed there, owing to the fact that it nearly is at the center of india.
For Blue Dart or Rather Blue Dart DHL
Hyd will have just Transiting 2 B732SFs.
Meanwhile if things go fine maybe Blue Dart DHL would add Two B752PFs to operate between MAA,BLR,BOM,DEL & leave Four B732SFs to connect Maa,Blr,Bom,Del,CCU.Hyd,Amd.
Considering DHL internationally will connect Bom & Del more frequently,that leaves Blue Dart DHL to operate their B752PFs when they arrive thru Bom & Del more frequently.
