Polish low cost carrier Centralwings is planning to more than double its fleet from five to 12 planes by 2006, its president and ceo Piotr Kociolek said.
By 2010, it was aiming to have a fleet of 24 planes, he said at a London press briefing.
It also plans to start new routes from Warsaw to Edinburgh and Shannon and from both Wroclaw and Katowice to Dublin later this year.
Frequencies on its key route from Warsaw to London Gatwick will be increased to two a day from November.
Other new routes include Wroclaw to Milan and Warsaw to Grenoble.
Mr Kociolek said the UK and Ireland were the carrier's key market and there had been a 265% growth in air traffic between Poland and London since January. Up to 30% of its business was to or from the UK.
He said the aim of the airline 100% owned by LOT Polish Airlines was to become the dominant low cost carrier in eastern and central Europe.
Its main competitors are SkyEurope Airlines based in Slovakia and the Hungarian-owned Wizz Air.
Centralwings, which began operations in February, has secured 14% of the Polish market and hopes to carry 1.6m passengers, including those on charter planes, next year.
But Mr Kociolek said that despite its “soft” alliance with Germanwings it had no plans to sign up with other low cost carriers.
“The â€˜wings' concept to create an alternative to the big flyers, an alliance of low cost carriers is still an idea that can be developed in the future but our co-operation with bmibaby is not developing very well,” he said.
He also said his airline had no specific plans to attract the business travellers although this was something it did intend to address.
