Hello and welcome! You have status with CO and they have a good product. Nothing is going to change anytime soon and many airlines have status match or elite qualifying runs for flyers looking to switch, so check out the options there before making a decision. We all hope that the 'new' DL product will incorporate many of the features of WP that make it an attractive program, but DL has a track record of devaluation over the years that leaves a lot to be considered down the road.
