As it is cold and rainy in London this morning, I am sure the climate in DEL is much more pleasant - enjoy your trip.
I agree with

Flower Duet from Lakme or something else calming, very much in the background, was pleasant - not so keen on the Jet Airways approach.
I am, however, keen on their approach to inflight catering, as very clearly set out in your post. I have only ever flown J (
