My guess...These purchases are for no other reason than to get around scope at DAL and UAL. In less than a year Republic will open a ATL base with 190's in Midwest paint operated under an at risk codeshare in order to drive Airtran down in ATL and MKE. What I thinks gonna happen with Frontier is a little more complex but with a similar intent...On another note unless your happy with a career at a regional I think its time to get out
