Ended up in a massive queue, to then wait to get our flight called to join another queue, to then wait and get called to just head straight to the gate and get our passport checked there. Made it, and it seems a lot of people are in the same boat so they are prepared to handle the rush, but it is a rush.
That, however, is a T5-T3 connection, which involves a bus. That connection was also 5 minutes over the MCT. But yes, OP, you may find quite a large queue at security. Thankfully BA tends to use the closer gates, but AA tends to use the far (30+) gates.
