I have checked two websites -
- RoyalSundram (http://www.royalsundaram.in/travel-shield/travel-shield-features.aspx)
Coverage - Trip Delay(After 12 hrs)
- TaTa-AIG ("http://www.tata-aiggeneral.com/tagic/Individual/travel/travel_guard.jsp)
Coverage -Trip Delay: Reimbursement of additional expenses occurred due to trip delay (only if the trip has been delayed for more than 12 hours).

So out of the three policies,(we have suggested) - ICICI Lombard' Travel Insurance is best for you as it's giving you coverage if there is delay for more than 6 hours.
