What is the fastest and most economical way to meet a Platinum Challenge?
HI-I tried to search the forum before posting this, but couldn't quite find the answer. Sorry if I am repeating what has alrady been posted. To meet the Platinum Challenge, would a RT flight from LAX to Narita or from SFO to London Heathrow on American do it? Would it need to be business class in order to have the right faire code? I am trying to figure out the most effective and economical way to do it with just one round trip.
Thanks,
