In reality it's all opinion, who saw 5/24 or Amex once in a lifetime ( with some exceptions years later) coming ?
We can't be the only people who have flown 50 plus free SW flights ( since 2013) and never paid for one flight which is more less impossible today on any other airline.
We have CP until 12/31/2019 and 500K plus WN points in stock so it won't effect us either way for a long time.
