Central European budget carrier Wizz Air is to open 10 new routes from Budapest, further reinforcing its base and filling more of the gaps left by the demise of Hungary's Malev.
The new services will restore a number of routes on which Malev had offered the only regular link, according to schedule service Innovata.
These include Sofia and Cluj as well as the Mediterranean cities of Larnaca and Thessaloniki.
Wizz will also operate to former Malev destinations Bucharest and Warsaw, plus Rhodes, Heraklion, Zakynthos and Malaga. It will station a sixth Airbus A320 at the Hungarian capital to provide the capacity.
The carrier will compete with Ryanair on several routes, following the Irish budget airline's decision to establish a strong presence at Budapest.
Ryanair and Wizz are both set to operate services to ex-Malev destinations Brussels, Gothenburg, London, Madrid, Milan, Rome, Stockholm, Warsaw and Thessaloniki.
There will also be a head-to-head battle on routes to Eindhoven, Barcelona, Bologna, Pisa, Palma, Malaga and Rhodes.
But Innovata data also indicates that some cities on Malev's network will remain without links to Budapest, among them Belgrade, Odessa, Sarajevo, Skopje, and Podgorica.
Wizz said it was interested in starting services to other former Malev destinations - such as Moscow, Kiev, Istanbul and Tel Aviv - if it could obtain regulatory clearance.
Its additional A320 will begin operating from Budapest from April this year.
