CYS put up ~600k in subsidy... I believe they were trying to re-attract AA or G4 to LAS and AA won out
The last time they tried this was like 2010/2011 after the recession as the industry started to regain traction, so maybe without ZK and given the economy it might do better this time around, but who knows. Great option for me though, I'm halfway b/w CYS and DEN...
Though as somebody noted on A.net, no idea why they didn't just go after UA to DEN or DL to SLC...way better connection points for CYS
