As a refugee coming over from the NW/DL merger, let me state this very categorically: After the merger DL smoothly integrated the elites and treated them relatively fair. But the award calendar went out of control and has never been fixed. Space is there, but never at advertised low levels.
With the UA/CO merger, everything has gone down the drain, but the awards calendar is still working and probably better than ever. And that's their only good point. Let's hope it doesn't change. So for one particular item ^ UAdbaCO.
