And if none of us know (which is the case) what will you do?

In case you missed it, the last AA award chart change (early this year) was not announced in advance; it was sprung on everyone "suddenly". We therefore have no idea if there will be any advance warning of any further award chart changes (should and when any occur).

Having said all that: They're busy implementing the merger, and probably have other things to worry about than tinkering more with the award chart, right this second. You can't make long term plans based on that, but maybe you can at least make short term plans.
