You're not alone. There has been discussion on and off in various threads on this topic over the last year. I was a 1K mostly through CM until this year, but I have not flown on CM since last May.

My company's travel policies only let me pay $100 more than the lowest cost carrier and it was getting more and more difficult to find a CM routing that met the requirement. And this is not on PTY flights where CM least has the advantage of offering non-stops from the USA vs. their competitors. My flights are from Colombia, so I always have to connect in PTY when flying CM.
