On this note, I will say that in T3 arrivals, I had to almost argue with the LHR agent to let me use Fast Track with my OWE status recently. She was claiming you could ONLY use it if you had an invitation from the crew on your flight.
She said they are more lenient at T5 (which is true, they always let OWE through), but at T3 they are more strict. Odd.
