For travel in February, you can get a Coach roundtrip between LAX and India for only 80K AAdvantage miles, by combining a North-America to Europe off-peak roundtrip award, with a Europe to India roundtrip award. (You can also get a European stopover this way, if desired.) The aa.com website will only show availability on AA/BA to Europe, and BA to India. If you call AA, you can check availability on other carriers from LAX to Europe (AB, IB, TN), and on other carriers from Europe to India. (Several AA partners fly to India; partner carrier 9W actually serves CCU.)
Flying through London is not particularly expensive; it's redeeming Avios that's expensive, because of the fuel surcharges that BA assesses when traveling on BA and on many of its partners.
