Hi eserifog
Congratulations on the interview.
We (Virgin Crew) operate from both LGW and LHR, although a majority of flights operate out of LHR. A typical roster will consist of 5 flights, although sometimes 6 and they will typically be a mix of flights from both LGW and LHR.
You can request days off after 6 months and trips after 12 months, however swapping trips with other Crew is very easy provided it is legal and doesnt waste days etc.. etc.. Most crew have a preference for one airport or the other and will often swap trips if possible. I prefer LGW trips for example and have names of a number of crew who prefer LHR trips and will try and swap at least one of my LHR trips per roster.
Virgin provide a Crew shuttle bus that operates between the two airports on an hourly basis throughout the day.
Good luck with the interview and if you have any other questions just shout. I cant help with interview tips as mine was some years ago but know there are loads of threads on her that should offer some help.
