This thread is about airports
Any airline management that would trade a superior economic airport / hub / focus for a inferior economic airport / hub / focus is going to have issues with its shareholders (unless it has a grant plan for changing that situation). Additionally such trades are not in the realm of possibilities or speculation.
The question in this thread is if and where should UA hubs (unlikely IMO) or focus city airports.
