<<without quota holding until after 0602.>>
To be absolutely accurate, the first ones come out of holding around 5.50 to be on the ground at 6.02. The 6.02 bit, instead of 6.00, was because thr airport authority would not accept the times issued by ATC. "06.00" in ATC parlance is from 05.59:31 to 06.00:30 (or within a second of those times). Can't recall why the extra minute was added but I think it was a BA thing??
