Guys, might be off topic (in that case actual mods kindly delete), after reading some posts I wanted to share something which may be important and applicable for others.
I have to courier my passport quite often to a travel agent. Normally I use Bluedart, they have a priority packet and they reach from a Tier 2 city to Mumbai in like 3 days max. In recent time, the travel agency was not able to ship it through Bluedart.
They used Professional Courier with their service called - Pro Premium . It states it is to be used for time sensitive and important documentations. And wow, 12 days of sleepless nights it was.
Once it was picked up, the tracking never went live for like 3-4 days. Then it showed until 11th day that it was in transit from Mumbai to Kolkata.
I tried contacting the central customer service, rarely they answer phone or reply to email. I called up Mumbai office, the center where the article was shipped from, the ProPremium desk, the Kolkata office. No one could give any info whatsoever.
So cutting to the chase, if you are ever faced with the proposition of couriering something valuable and very important, please do not fall for this service. Professional Courier - ProPremium.
Reliability wise (connection to tier-2 city) I'd have the following rank:
1. Bluedart (Expensive, but peace of mind, and incredibly fast)
2. Delhivery (Cheap, good connectivity)
3. First Flight (not sure if they are open anymore, they were very fast)
4. DTDC (IMO, Delhivery surface is faster than DTDC Surface)
* GoJavas was good and fast, then Snapdeal ruined it.
I think DTDC tracking system is excellent. Per se if shipment coming via air, their internal tracking system even records the flight number where the article is travelling)
