Really? The average time from start approved to airborne on RW27 is 12-13mins. Given the start takes around 4mins (from approval to requesting taxi) then you're talking about 8-9mins of taxi until airborne.
Granted that's an average, less in quiet periods, more in busy periods, but I think the 95th percentile of all start to airborne on RW27 is around 15mins. I don't imagine LHR comes close to that.
Perception of "delay" is an interesting subject, esp. when considered alongside On Time Performance.
