Indeed the TATL is in a bit of flux ex MAN right now. TCX and VIR have massively increased capacity. We've seen UA react by dropping IAD, the VIR/DAL partnership needs to settle, and if successful who knows where else VIR could add. NAX/NAI is an unproven concept, operating to these regional US airports could suck up all the low hanging VFR traffic, or it could fall on its' face after a couple of years if people decide it's worth paying a bit more to fly to JFK/BOS, and in the meantime UA, AA May reduce further.
A bit of stability could be a good thing long term
