Swiss regional carrier SkyWork Airlines is hoping its planned expansion will lead it to become profitable next year.
The Berne-based operator grew its Bombardier Q400 and Dornier 328 turboprop fleet from two to six aircraft last year.
Passenger numbers more than doubled to around 87,600 compared with 2010, which was mainly attributable to a larger route network.
However, the average load factor was only 50%. The most successful routes are from Berne to Belgrade and London City Airport, which registered load factors of around 76% and 77%, respectively.
Also the workforce doubled to 147 staff members, with more employees expected to join this year.
The airline plans to expand its route network of 11 destinations to 25 locations in the summer.
The company is "aiming for a break-even result" in 2013, said chief executive Tomislav Lang.
