Thats what I had originally thought so I checked all other flights that day to DEL and they all left on time.
Reason why I ask is that I fly quite often on this route and sometimes I need to cash in some vouchers for an upgrade. So if an empty flight in the morning turns up to be fully booked by the evening that doesn't give me much hope for upgrading.
