Did you use the same boarding pass at T2 security? Was thinking of just printing twice or using electtronic. Thanks
Yes, same boarding pass. The TSA agent made a comment about me "going back in again" when I went into T2 at which point I said that I'd been into T1 to get to the lounge. No issue at all.
I used the same boarding pass 3 times at SFO recently during a delay (T3, then T1 to get to the Alaska lounge, then T3 again) and didn't have any issues.
