Hi Virgin Girlie,
Congratulations on getting the job
We are dual based at LGW and LHR. There is no easy answer to the question of where is the best place to live as we have crew who live all over the UK (and some even further afield).
For the training course I would advise staying close to LGW as there is a lot to take in everyday without the added stress of a commute to/from The Base .
Although most of our flights depart from LHR you will be probably be rostered a fair amount of LGW flights as well because of the high number of Cabin Crew (formerly known as Junior) positions on the LGW based 747s.
Virgin operate an hourly shuttle bus service between the LHR and LGW so it's not too difficult to get from one airport to the other.
Hope this helps
