amoungthestars,
I have an interview with Virgin on the 25th and have the same deliema as yourself, I'm about a 10 - 12 and am fearing turning up on the day to find myself amoungst the most beautiful looking women 18, blonde, big boobs and small waists!
Will go anyway and let you know how far I get. If airlines go entirely on looks that they bring a whole new meaning to the 'trolly dolly' label.
