I don't know, it sounds awfully line an agenda-driven set of premises to me. And, unless I'm hallucinating (entirely possible) you've alluded to not being an Indigo fan several times in the past.

What's the point of the article anyway? And it's perspective? Because the conclusions too seem to have been decided already, with the fillers just there to take up room.

I've never flown Indigo (or Kingfisher for that matter) but by all accounts, the increasing number of people who do choose to fly them do so because 6E do exactly what they say on the tin : provide an efficient, reliable, largely nakhra-free means of getting from Point A to Point B. That is a rock-solid foundation to start with, something Kingfisher never had.

Interestingly - and this is my opinion only - it's Jet who have done Indigo one of the greatest favours by accelerated the acceptability of flying an LCC for so many people who wouldn't have done so as quickly if they weren't pushed in that direction by Jet.
