Xenia....in the debate of MXP v BGY perhaps I should point out that MXP is 30miles from Milan and BGY is 28miles....not really a massive geographical difference!...infact quite the opposite.
Yes, accepted that it may be easier to get into the centre of Milan from MXP given that it's a larger airport with possibly better transport links, however BGY tends to be favoured as a better route regards winter ski traffic and therefore a better option operationally for Flybe. and certainly for year-round passenger traffic.
