From the earlier Air India BKK-DEL episode cited above:
Minutes after his co-pilot left the cockpit, Captain B K Soni called another flight attendant, Kanika Kala, and asked her to take his seat. Captain Soni did not leave the cockpit immediately; instead, he spent a few minutes teaching the two flight attendants how to operate the aircraft.
He left the cockpit after putting the plane on auto-pilot, leaving the flight attendants to operate the flight by themselves for the next 40 minutes while he and his co-pilot took a nap in business class.

At least the, uh, Commander gave the air hostesses some dual on how to fly a plane before he left.
