The Kiev-based subsidiary of Wizz Air is seeking the right to operate on major international routes abandoned by financially troubled AeroSvit.
Wizz Air's Ukrainian division has applied for permission to serve 18 destinations which AeroSvit ceased serving after it filed for bankruptcy protection on 29 December.
These include six European capital cities as well as St Petersburg, Naples, Larnaca, Saloniki, Baku, Yerevan, Batumi, Tel Aviv and Dubai.
"We want to fly to the cities which are not served [from Ukraine] anymore or are clearly under-served," says Wizz Air Ukraine director Akosh Bush.
"We hope to obtain regulatory approval within the next few weeks."
At present, the carrier only operates on routes to a handful of second-tier airports in Germany, Italy, Spain and Poland, deploying two Airbus A320s.
But it plans to bring in a third A320 in March and a fourth in July, says Bush. He adds that expanding capacity will allow it to increase annual traffic to 1.3 million passengers.
Bush says that fleet growth and related costs should not entail adding: "Our pricing policy will remain in-tact and fares will not grow."
