A bit older but never the less:
Skopje gets a second a/c from April 2014
WIZZ AIR DOUBLES FLEET IN MACEDONIA
October: new base at Donetsk (1st a/c)
March: BUD 8th a/c
April: SKP 2nd a/c
May: WAW/WMI 4th a/c; SOF 4th a/c
New interesting markets (cause of less competition from FR or EZY) like Tuzla, Kosice, Chisinau, Tel Aviv, Istanbul, Dubai, Baku or Moscow will be added to the network with more to follow (rumoured: Astana, Yerevan, Minsk, St. Pertersburg).
