Southampton seems to be quite happy putting all its eggs in one basket with regards to the principle airline using it going back over many years. Air uk, BA express and now flybe. It seems to me that new routes are few and far betwen and rarely last long for a number of reasons. I did the bmi route sou to muc last year and timings worked well but had a poor load (22 people inc 8 in a stag party) so no wonder it has been pulled this year.
