Reading through all these topics here (it's almost too much information to grasp), it seems like so many people want to switch airlines. I know you can't please all of the people all of the time, but how do people make up their minds on which airlines to switch to? The only airline I can reasonably switch to is US from DL. But with the news that US is selling their gates, commuter airline and hubs, switching to them is a scarey option.
