I'm flying with Air India and I was looking in which loyalty programs Air India is a member. It turned out, that Air India has its own loyalty program called "Flying Return". From the homepage, it appears that Air India is the only airline that is part of "Flying Return".
Since I don't plan to fly again with Air India, this wouldn't be a good choice for me. So my question is: Is it really true that when flying with Air India, you can only earn miles for "Flying Return"?
