In the past all 3 had FF programs that were worse than any of the OW airlines. Some changes in the FF programs are obviously needed upon entry to OW, whether these will make it 100% better is somewhat doubtful. From a FF plan shopping viewpoint, it doesn't seem to be much of an opportunity. The JL plan makes QFF look very generous, so if anything it might spur a new round of cuts in FF benefits at the other OW airlines.
