When they pulled out, Southwest moved in and Delta increased their flights. Now we have people from Ohio and even New York driving to Pittsburgh for better air fares.
USeless Air still has a large number of flights here, but I've managed to avoid them all except once (a business flight to Philly where the company picked the airline).
We are blessed with one of the best airports in the country even though we are still under capacity. We have a world class airport mall which was swamped with visitors and shoppers a few days ago when non-ticketed passengers were allowed past security. It went off without a hitch . . . which makes you really wonder why the TSA is even necessary.
Sacramento Airport used to advertise. People in Sacto knew you could fly much cheaper from SF or Oakland.
After PSA and AirCal died and Southwest exploded, it saved the Sacramento airport. When they built a new terminal they gave most of the gates to Southwest. Now they have built another and southwest runs that too.
