I read and didn't see Air India. Maybe I missed it or maybe people don't like it.
I have flown with them a few times and really like their biz class. Yes, others are a bit more luxurious, but Air India's biz class prices are very cheap and IF you like Indian food, it's pretty good.
Additionally, at the chaotic BOM airport counter, they'll take very good care of you. They assign a helper who will follow you carrying your bags and also to make sure that you get through security quickly. (So make sure you don't get of all of your rupees when you leave! I tipped fairly well because those guys are great!)
(I also am a sucker for airlines that give you pajamas.. I still wear my Air India cargo sweatpants around the house!)
However, if you don't like Indian food, don't even consider as their western options are limited.
