After landing, another long long walk to transit security. This time with BP pass in hand, no need to stop at transit counter. It took about 20 mins to go through the security - about 20-30 people in the queue in front of me, then of course all the stamps - for the hand luggage and the boarding pass!
I then proceeded to the Air India lounge. My first question - was there a shower? Yes - but it's out of order!
Seats were comfortable enough, there were some recliner chairs which were good, but food selection was ordinary and the hot food cold.
After a couple of hours I went for a walk around the airport, stopped in at the bookstore to buy some books (they are usually cheap) and a can of coke (the only place in the airport, apart from McDonalds, who had post-mix) that stocked Coke, all the lounges and other F&B outlets only stocked Pepsi.
As my credit card comes with two complimentary Priority Pass lounge visits a year, I found the Plaza Premium Lounge, near the transit hotel, where I had a nice long shower! FWIW, with no lounge access you can still pay for a shower for 700 INR (~$12AUD). Food was also better here than in the Air India lounge. Internet access was a pain to start - you need SMS verification and it didn't work on my Singapore mobile, but the lounge assistant was able to help.
After a while there, I then moved to the SQ lounge on the floor below, courtesy of Star Gold status with SQ. It was very much like the refurbished MEL J lounge. The base food selection was the same as the Plaza Premium lounge, but the SQ lounge had a few extras as well. Also some better quality beverages. After they called the SQ flight I then went back to the AI lounge for an hour, where I relaxed again on the recliner seats.
I think if I did this again, I would consider paying the $100 or so to get a room the transit hotel, maybe get some shuteye from 4-10pm. Otherwise, with hand luggage only, I would think about trying to sacrifice the last sector and get on the MH flight that was leaving 2 hours after I landed, that would get me back to SIN that night. But I suspect, whilst this approach could work at places like SIN, this may be impossible at DEL!
Hardly anything to report on the last flight, it was full though. I only had pre-takeoff beverages and the bottle of water provided in each seat, skipped the meal and went to sleep. Probably the biggest concern for the whole trip came in the last six minutes, I had woken, a looked at my watch thinking "we must be landing soon", and out the window I could see the part of Malaysia you usually reach close to final approach. Sure enough, on came the captain "6 minutes to landing", so the crew hurriedly got everyone's seats upright, stowed everything and had 3 minutes to spare pre-landing. I am more used to the SQ announcement "30 minutes to landing, cabin crew prepare cabin for arrival".
