I flew IT2 LHR-BLR back in November 2008 on an NW award. I realize that it was close to a year now, but holy crap, it was awesome. (Note: I've never been in a true premium F cabin, ala SQ, so take that for what it's worth.)

IT provides a flat bed on their premium A330 product. There's a 15" or TV at the end of the bed. They serve a very good multi-course Indian dinner. There's a bar in the premium cabin with free alcohol. They give pajamas. Very good mixed drinks. Excellent service. The lounge at BLR is better than anything I have ever seen in the USA.
