The only thing really worth while in ASK PIEDMONT dealt with LGA closing. Pretty much they were expecting approval of the swap to come last month but it has been delayed (for once I'm happy the gov't is dragging their feet) however if it gets approved they believe all planes will be relocated throughout CLT and PHL, primarily CLT with limited exposure in DCA.
As for the MESA stuff, I believe all that happened after answers were submitted but it might get some interesting questions next week.
