Thanks - I had an In-Transit pass, the problem was general boarding had started and the long security Iines. Even the suite/Pinnace/Key security line was long and slow. I was hoping the folks in from of me with 3 kids, two strollers, two carry ons, soda, water etc would see me and let me go before them, but no. (I never asked). Once I got in the terminal, of course I did not need to check in, and I was able to find a shorter line to get back on. Agents allowing folks on board seemed perplexed that I had a sea pass card to scan.
Last time I did this, I was able to get off just before the B2B group, and was back in the terminal while the B2B were still waiting to reboard. They let me back in the B2B group to get on board. EASY
