If you decide to go to TBIT, walk and do not wait for the connection bus. Two hours might be pushing it, so you may want to avoid this altogether.
The hidden TSA
Checkpoint Monsters can be avoided when taking the elevator directly to Mezzanine so the officers won't even be around to engage you.
Terminal 1 is very crowded versus Terminal 5, for example, so I would consider staying within the secure area. The local news come Thanksgiving and Christmas Holiday will always stand outside of Terminal 1 saying, "arrive at the airport at least 4 hours in advance..." When you have low-cost airlines, they attract a higher percentage of passengers, so expect heavy wait times at TSA
And, please don't waste your money on the offerings at Terminal 1. Find a bar and drink. Your SFO
flight will be over before you know it and you'll far appreciate 'saving room' for the delicious cuisine SF
has to offer!!!
Enjoy your travels!!!
Just an FYI, if you take the elevator located just west of the WN
Tix Counters, you can avoid the TSA
Agents altogether giving you the choice of the hidden screening area. This is my little insider tip for the one time I had to go through the very sad terminal.
