Oh that may be too tedious. I have to send a friend off with delta flight T3 and T2. My thought is to go with him past security, then when he’s off, I walk to T7 or shuttle to T7, then walk to TBiT for flight. Based on what you said, I have to go to T2 or 3 first the shuttle to TBIT then walk to T7 and back. Lots of work. Thanks for answering though.
