A recent experience, came into T3 with AA going to T5 BA. I was down to 1hr10 minute connection, as the inbound was delayed.
At the exit of the aircraft I was handed an orange "oneworld express connection" paper sleeve and told to keep it visible at all times, along with instructions on where to go by the AA agent.
Once at Terminal 5 another BA agent with the flight number/destination, was waiting for me and escorted me through security (a distinctive line for this).
I'm not sure if this is for all oneworld connections or only AA/BA/IB ones. The overall process was efficient, although falls short of what AF do when you are on a 45 minute connection at CDG (bring a car to your inbound aircraft, drive you immigration and subsequently escort you right through to the gate). I'm not sure why oneworld do not do this, maybe BAA is opposed to the idea?
