Wow, thanks for all the warm welcomes! Much appreciated.
As far as the OP, a couple of people have asked-- there may be a case of a few agents acting as "vigilantes" -- either taking it upon themselves to enforce a rule that they believe should exist, -or, more likely, simply confusing the rules of an all-partner award with a OW award.
There has been this issue-- picking up lately-- where people are taking multi-segment "awards to nowhere" where they are routing so that they get the maximum number of flights taking advantage of the soon-to-change rules. I have heard faint rumblings that there might be some stop-gap measure between now and the change in the fall to reject some of the more ridiculous itins-- but that certainly wouldn't apply to someone simply trying to get from there to here using the existing rules to their advantage.
Trust me, if this rule was in place 'till now (direct routing) none of these "enthusiasts" that have gotten those itins approved (and many have) would have.
I also noticed that the routing rules for the OW awards has very recently been changed on AA dot com for pre-change awards to, essentially, "call for routing" (from the old rules, which I believe were spelled out.) Does this mean a change is about to be implemented? Not from what I'm hearing so far, although the fact that this issue is being "discussed" within AAdvantage is not in doubt, I know it for a fact.
However, no one I've asked has confirmed that any restriction of this type is coming (NOT referring here to the change we -know- is coming.) Personally, I wonder if something won't be done to limit the losses before the change-- but hasn't happened yet form everyone I've asked.
