Having experienced both MON and FCA (pre-cabin upgrade but not premium) on Gatwick-Male I would choose FCA. Also the FCA flight operates to an earlier schedule which may be more convenient. Having said that, going out I don't mind too much as knowing what's at the destination tends to make you forget the flight experience. It's the coming back that matters as it takes possibly up 1 hour longer due headwinds and you want a good flight experience to help deal with the thought of returning home from such a beautiful area.
