My parents are coming BOM - LHR - LAX in next few weeks. Mom is a vegetarian and dad eats chicken,fish, egg but no other meat. I requested "Asian vegetarian" for mom and "Hindu" for dad. The details I am getting are a little confusing. Does the Hindu meal have meat(chicken or fish )? Is Asian vegetarian really Indian vegetarian food?

The LHR - LAX flight is operated by AA.
