@CaptScott...You can ignore my paranoidal, delusional, theoretical post if it would make you happy...
Its been stated before that ALGT may be looking at the Airbus. They may have invited NK management over simply to talk about the growing pains/lessons learned of transitioning from a Mad Dog fleet to an Airbus fleet. I think Spirit did that transition quite successfully and may have something to share on a professional level with a company like ALGT.
Point is...just because two managements meet, doesn't necessarily mean there is a plot or something big planned (or something I can turn into a delusional theory!!). They could be discussing a number of things that companies do all the time on a professional courtesy basis.
