FYI-
The AMA has rules to insure that contests don't get sanctioned in a manner that they occur on the same date within proximity of one another. According to the class of the contests, A, AA, AAA, etc, the minimum distances between contests vary.
Also, taken into account is the timeframe the contests have been previously held, a contest can be labeled a "Traditional" meet if it's been held many years, for example.
In addition, the timely manner in which the AMA sanction is granted gets into the mix.
As the CD for the "Labor Day" Dallas contest*, I've noted the Stunt Team Trials being held in Tulsa (a GREAT venue, by the way) and have contacted AMA to see what happens if a conflict with Team Trials and a "Traditional" contest occurs. The Team Trials are AMA sanctioned. I've not heard back yet, but, I've pored over the rules and there is a sentence I don't fully understand concerning "FAI" contests. AMA is looking at that, too.
Situations such as these are the reason why CDs get the big bucks!

*FYI: The title for this meet isn't actually "Labor Day Contest", it is the "Charles Ash Memorial/Southwest Model Airplane Championships". It always will be the "Soutwesterns". Try to get all that on a trophy!
