When I'm out on the tarmac at SJC terminal C disembarking via the airstairs, I could make a run for terminal A, but there aren't many ground level entrances over there
At least the UA/NW/CO/US portion of SJC is now behind the same security checkpoint as AS/DL.
OAK, DEN, IAD, ATL. Are we counting CLE, PHL, CLT, PIT - which are all just different arms off of one beast? Or MSP which is just a big donut with legs? Not counting AUS, SNA, PVD, BUF, etc - they aren't really different concourses. Similarly not counting airprots like CIC. MCI is the anti-connected airport.
