Even on time can be tight. Just did MXP-LHR-DFW (biz so first off BA). Plane late, bus to Terminal, then got a wasted "Express Connections" paper. Bus to Term for AA flight. Then over enthusiastic security people asking 10 questions, then AA counter for new BP and verify baggage tag, then security (and Express Connections did nothing). 1 lane for Fast Track and 1 for everyone else. Had multiple people on AA flight. About 30 people and moving slowly. Finally they let us cut ahead of about 7 people who were not happy. Ran to gate and we were last ones on. 90 minutes is what you should have.
You really can't make it faster than it happens to be that day. Good luck.
==sorry misread- Mine was Terminal 5 to Terminal 3
