People are ready to pay a premium for a prompt and delightful service, but unfortunately Blue Dart Courier is one courier carrier who charges premium as well as disappoints its customers as well. I would rather suggest everyone to try a Blazeflash or a Professional Courier service. They are much more professional and punctual than Blue Dart. Blue Dart is defenately not a value for money.
And trust me, if you are really good with your luck, you will get your shipment delivered on time, or else, keep atleast 3 days buffer in hand for the delivery (their flights usually gets cancelled due to "technical issues" or the shipment usually "arrives late" at the destination and the best part is that they lie to you saying it has reached and will be delivered on time and right at the delivery time you shall come to know that the delivery has been postponed.
My personal view and suggestion: Do not go with blue dart, try anything but not blue dart- one of my worst experiences amongst courier carriers in my life!
Hope you find it useful!
