Hundreds of Russian and Finnish tourists are stranded in Bulgaria after their charter flights were cancelled in a row over payments between the tour operator and the carrier.
Privately owned Bulgaria Air cancelled four flights claiming that bills totalling 3.5 million euros have not been paid by the travel company Alma Tours.
In a statement Alma said it regretted the distress to tourists caused by the dispute, adding that that it hoped a compromise could be reached to get the passengers back home.
The company said it is paying for hotels and food for the holiday-makers, who are stranded in the Black Sea port of Burgas.
Bulgaria has been struggling to lure tourists back to its coastal resorts since the global credit crisis hit the industry hard two years ago.
Bulgaria Air says it has now rescheduled the cancelled flights and hopes to get the stranded tourists back home sometime on Monday.
