Thank you and I have a couple more questions.
1. I can take the air train from terminal C (where I assume the United Club is located) to any other terminals? So to access the AirTrain, I would have to exit the airside?
2. Is walking easier/faster/possible from terminal to terminal (I only have a carry-on)? Do I have to exit to the street to enter another terminal?
3. IF my flight is at 7 pm, should I leave the lounge and head to the Alaska gate at around 5:30 pm?
