Not sure Cardiff is CAA A380 approved yet ?
LGW,MAN, and BHX are .
How about PIK, BA have recently opened a maintainance base there. At the moment it is used along with the maintainance facility at GLA for A320 family and 737 engineering work.
Wonder if PIK is were the A380's will end up being maintained.
Nothing has yet been confirmed regarding BA A380 flights prior to entering long haul service although on other aviation site forums Frankfurt has been mentioned most probably the BA 902/903.
BA902/BA903 rotation looking more likely.
BA have just retimed the BA902 and BA903 starting the 31 July. However flights still showing as 767 operated. The retiming of the flights will see the turnaround time in FRA extended from 1hr 10 to 1hr 40. Which is plenty of time to turn around the A380.
Until 30th July
BA902 LHR 07:00 FRA 09:45 767 D
BA903 FRA 10:55 LHR 11:40 767 D
From 31st July
BA902 LHR 06:45 FRA 09:30 767 D
BA903 FRA 11:10 LHR 11:50 767 D
