In case someone has not heard the news, Kingfisher is scheduled to join one world, presumably at the end of February, assuming that the airline is still operating then. Presumably this may mean that DL miles will not be valid for award tickets on Kingfisher issued after some date to be announced. So, plan ahead if you are considering an award ticket that might involve travel using Kingfisher. Note that Kingfisher is currently one of the independent airlines that do not belong to SkyTeam or any other alliance. However, they have been a DL partner.
