I had the bizarre experience last week of my suitcase coming out within about 20 minutes of the BA108 landing at a B Gate and all the F suitcases actually coming out first to boot. Was speechless, it's literally half the time it has taken for the next shortest luggage wait for about two years at T5. I assume I am now overdue a two hour wait or lost suitcase as karma, though...

I agree that one should complain whenever the luggage wait much exceeds an hour from landing, that is not acceptable.
