I flew some segments on IT in J between DEL-BOM-DEL recently, and was quite impressed. Certainly sets new standards for domestic J travel in India, and comfortably beats both 9W and IC IMHO. The inflight entertainment and the significantly superior seat comfort being the two major factors where IT wins easily.

I was pleased enough after those two IT flights to buy a "First Advantage" booklet on IT with 8 J coupons. Previously I was using the 9W J class booklets, but I'm certainly not going to do those anymore. Atleast not as long as the fares on 9W are similar to IT.
