Danube
Sad news but they have probably realised what they had taken on-leasing costs etc.They are after all a small regional airline.
The summer rotations for the leased 737 appeared only to be to Luton and Dublin (4 flights a week in total i think) as Manchester had been dropped, so what was planned for the remaining days we will never know.
I wonder if Wizz might consider taking up the route as loads appeared good when Sky Europe were flying to Tatry.
