Low-cost airline Germanwings, part of Lufthansa, and new Polish budget carrier Centralwings, owned by Poland's national airline LOT, said on Tuesday they will cooperate on sales and marketing.

"We will use a single computer and reservation system, and this will be the first visible effect of our cooperation," Centralwings CEO Piotr Kociolek said at a joint news conference.

Centralwings, which plans to take off in February, will offer flights from Warsaw to Hannover and Nuremberg, and from Katowice to Cologne/Bonn and Hannover. Germanwings already flies from Cologne/Bonn and Stuttgart to Warsaw and Krakow.

Germanwings carried 3.5 million passengers last year and has 14 aircraft, while Centralwings plans to carry 800,000 passengers in its first year, operating five planes.

Poland's LOT is a member of the Lufthansa-led Star Alliance.
