Welcome doho! Nice to have another level-headed participant.
BTW, were you told about the initiation fee? It is to be paid in Swiss Chocolate to all flyertalkers whose screen names begin with "k."
As for your specific question, I agree that even the best estimates you will get from Randy will be just that: estimates. I for one would not bet the chocolate shoppe based on even his numbers. Just as an example, I've spoken with lobbyists for UA who claim that there are in 2000 33,000 1k flyers. About 2 weeks later I sat on a flight SJU-ORD next to a corporate trainer for UA (who was very mellow and forthcoming returing from the V.I.) who said that figure was more like 50,000 1ks. If the people inside the organization have such wildly varying numbers, then I doubt anyone outside the company has anywhere near accuarate info, IMHO.
And, BTW, sorry for not responding immediately. I am now more fully aware of my obligations.
