I'm flying my parents round the world (west-bound) with American Airlines miles redemption in February 2015. I already have Cathay in First US to Hong Kong, Cathay business HKG to Delhi, and looking at India (BOM or DEL) to Miami and figured LHR would be the best connection. I can redeem on BA or Jet and wondered which First Class fellow FTers think is best? Appreciate any input.
