Wizz Air continues its Eastern European expansion, this time in Bulgaria

Wizz Air is pursuing further expansion in the Eastern European market with recently announced plans to grow its Sofia base in 2013 and 2014. The expansion will see the low-cost carrier base a fourth aircraft at the Bulgarian capital and launch two new routes, as well as increase frequencies on four existing routes.

The expansion will focus mainly on Western European destinations, including a new twice weekly flight to Malmo in Sweden. But there will also be a new thrice weekly link from Sofia to Dubai's new airport.

Wizz's expansion places further pressure on flag carrier Bulgaria Air, which currently accounts for 26% of capacity in its home market.
