The current C terminal is a poor design for today's world (with multiple security areas, somme of which don't even have restrooms beyond security). The midfield terminal will be a good replacement for that, and hopefully stimulate a bit more business.
I hope they continue to scale back the grandiose plans that were originally envisioned, though. SJC
is clearly going to be a smaller regional airport for some time. With the end of AA
flights in October, the only widebody pax machine will be HA
's daily flight.
