I couldn’t find the FRA connection thread unless it’s in the LH forum, though LH isn’t part of this scenario but feel free to move it if necessary.

Around late December we might be flying DEN-FRA-BAH, with DEN-FRA on UA and FRA-BAH on GF. All on a single reservation.

My understanding is the first flight arrives into FRA at terminal 1 and the second departs from terminal 2. The scheduled connection time is 85 minutes, too.

I’m posting to ask about the process of changing terminals, which I’ve never done there, but it seems like it would be using the SkyLine. Is that going to be airside? And I’m also wondering about security and the fast lanes. If someone is connecting in the way I described, where would the security part be?
