Such a shock to see a so well established part of aviation in Southampton go. Have had a look over some of the routes flown by them over the years, and it is quite a list (I am aware some were served by Blue Islands/Eastern as franchises at times). Fingers crossed by S21 there is another carrier basing a few aircraft in SOU, hopefully departing from the freshly extended runway...
