And then there are those of us who fly a lot, and our travel patterns and location just result in more flying concentrated on one airline or alliance (in my case, UA), and earning higher status on that airline because of it. That I buy a lot of paid F also helps. I'll take the perks if they give them to me, but no loyalty whatsoever. If AA, Alaska, AF or KLM has the best route or a cheap business or domestic first ticket, I will fly them, and I do have flights planned on them for this summer. If you are in the front cabin, you are treated about the same as someone with status anyway. (But I generally will not fly Southwest, Spirit or Frontier - no protection against IRROPs, poor service except Southwest.) I cannot even imagine doing a mileage run.
