I agree wholeheartedly with the sentiment that Delta One Suites is basically a different product than their other seats. The sad reality of aviation is that most airlines have no fleet consistency, but continue to market their best seats everywhere to lure in consumers. And then they basically can do whatever once they take your money. You could go from Qatar's QSuites to a 2-2-2 config. Delta One Suites to their 763s.
And there is no consumer protections for it at all, which is very infuriating.
