Bumping this thread for advice. I am considering a Schengen-to-Non-Schengen (WAW operated by LO to DL operated US flight) connection on separate tickets within T1 at MXP with 2 hours. Hold US passport. No checked bags and will use online/app check in. Expect to arrive to MXP on A5-A8 area (possibly bus as it's E190) and depart on DL, which seems to use B51 or B72 or thereabouts.

Is 2 hrs enough time? Do I need to exit and originate as a "local"/Milan originating passenger, or is there a transfer path all the way from A gates over to B gates? Do I need to clear security again or just the passport control to exit Italy? TIA!
