I see no good reason why.

Maybe you can substantiate why they would do that. Dropping speculative hints like that (at least for the 2nd time on this thread), trying to make it an accepted fact, reduces your credibility much more than it reduces the credibility of the MEC.

Maybe LAS based pilots would feel disenfranchised if the meeting was held in DFW. I sure feel disenfranchised being a commuter, not being able to attend and vote in these kind of meetings. But this is no conspiracy, it is simply the way the organization is set up. This is nothing new, as far as I can tell.
