Going to need to go from HKG<->LHR, have a choice of the BA27/28/31/32 which basically have exact same departing/arrival times.

Q1, why have them have exactly same departure/arrival times? Why not spread them out throughout the day? Wouldn't it capture more market share from CX by giving travellers more option?

Q2, which flight should I take for Economy, the A380 or 777?
