Fair enough

The 6 Sunday departures SNN-BHX that I witnessed last year were always less than half full. I found that poor. I talked to some of the passengers a few times (who were mainly Irish living in Birmingham) and it's true their general impression was that the loads were "... awwwright like".
But I admit, I only saw 6 flights out of I don't know how many.
Just my impression. I think a BHX-SNN could definitely work anyway
