regrettably I am not a crappy junior working in one of the best school in UK.
Airlines are more and more aware of the quality that Bristol.GS provides, I can tell you that being an ex-student of Bristol, it is a big plus during selection process.
I do not say that Oxford is bad, I don't know Oxford, I can not judge( I have eared only good things about their grounschool too) , but Bristol has an excellent reputation in the airline industry so consider their offer even if it is a residential course.(you will save big money for your MCC!!)
I have been surprised when an airline did some very good comments on them.
to all of you:
