My advice is..... Go for the older ones... The older cabin crews.... Slightly more difficult to get but once gotten.... Can have more than just 1 bonk....
And these words were from a friend of mine who was a crew..... 'If you want just a bonk from a cabin crew, nothing long term, you dun have to be rich. You just need to act/pretend you are rich. If they think you are worth 'investing' in, you get your free bonk/S'.....
