TBIT to T7: possible airside?
I will be arriving on LH at TBIT. I know I have to claim bags then clear CBP on arrival. But I do have a connecting flight on UA.
Do I just walk all the way land-side to T7 and re-clear security there? Or can I go up to security at TBIT and is there a tunnel all the way to T7? (I do have to check-ins, plus a roll aboard).
