I don't foresee JetBlue and Southwest merging. The fleets are totally different, however Southwest did acquire AirTran and then dump the aircraft, so who knows. I think JetBlue and Virgin merging is more likely as their fleets would go well together. As for the earlier post saying that JetBlue would take the Virgin name... possible but not likely with Delta having major ownership of Virgin Atlantic. A larger domestic competitor with the Virgin name would likely not go over too well with Delta management. Hell, Delta could always just buy Virgin America...
I'd like to see Alaska, Southwest, and Hawaiian merge and we could call the new company PanAm
