I hear that Air Baltic maybe about to launch a return into Man. during March with a three times a week service to Riga and two to Vilnius.
.
VNO now confirmed (didn't check RIX as I'm on LT's side
), Thu/Sat, wait, depending on how you look at it it's Fri/Sun. Departing MAN at 0:50, arriving MAN at 0:10. Don't think even FR has such aircraft utilisation - even through the night.
