I was going to do a quick trip to Bombay and Lucknow during my visit to BLR. I only have a 2 days and needed to be back Monday by noon to catch my flight back from BLR. I was wondering if the connection in DEL would be ok (I could also connect in BOM on my return) and what's the risk of irr ops with Jet ?

I hate to throw a dampener in here, but your flights are all Jet Konnect or Jet Lite. Of late, these haven't had a great track record for on-time performance. Plus, evening arrivals and departures in and out of DEL are usually delayed for some reason or the other (now that "winter" has started, this means that the morning flight was delayed and that causes a domino effect). So the 50m layover in DEL would be cutting it a bit too fine, in my view.

Thanks. On the return from LKO is there a change of planes in DEL ? The flight numbers are the same but the website doesn't make it clear.

You're right, there mostly won't be a change in metal used. However, that doesn't stop both inbound and outbound delays from DEL.
