What is the best airline to travel from USA to India?

Which has good services and reasonable fares?
i am also tall so need leg space but i could get the exit row to make up for that

The carrier which will take you there safely. Not many flies from the US to India, so you choice are narrowed.
If you want to be comfortable and good service, my only advice...buy Business or First Class ticket, so you won't complain later how bad your flight was, because you were cramped on a coach seat

A few that i have found good are:
British, KLM, Gulf

The worst that i have found is Air India. They treat you like dirt.
