As for keeping a PNR on everyone, yes there is a profile that gets built up. As for nasty notes about those who have done the MHD, not sure about this. All I know is I still get treated very nicely by AC, and the res agent I was talking to to make a change in one of my bookings a few days after I hit SE congratulated me and was quite sincere in marvelling how much travelling this would have entailed to achieve by July. Had there been a MHD note on my file -- and assuming the agents would even know what it meant -- he'd have been more likely to curse me and treat me like the Baby Boomer/Yuppie scum that I am. In fact, like KH, there is a streak of Yippie in the whole way we approach our need to travel for a livelihood. [Sorry, was watching a movie on cable about Abbie Hoffman last night...]
