Back to the merger speculation.....Everyone seems to think that UA-CO will merge which will leave US out to dry. It seems to be the better option is for CO-US to merge. We are the two smallest carriers of the remaining Legacy's and UA is big enough to stand alone. This would leave four strong large airlines....DL, AA, UA and (US or CO)...which ever name survives...This union would likely drop either EWR or PHL and keep the other one but would still have DCA, CLT, IAH and PHX...A good structure to build with.
