Yesterday morning I wrote that I would be flying Delta domestically for the first time since 2010. While I’ve found SkyMiles to be the least rewarding major frequent flyer program in the US, even now that United and American have largely mirrored the model of moving to revenue-based earning, devalued award charts, and reduced availability, they’ve had the best airline operation of the US majors.
So you choose to fly Delta for flights that aren’t cancelled, and largely operate on time, not for the miles.
