For years Tarom used to serve MAN-OTP, it has been gone a while admittedly but you can't help feeling the market it served is probably still there? Since (if I remember correctly) there's no other Bucharest service from anywhere outside London then surely Blue Air should be a strong contender for an MAG "group" deal to coax them into serving both STN and MAN. There are probably a few others on the fringes of Europe a la Air Moldova who have monopoly routes into London who might be pursuaded similarly (perhaps Belavia?)
