Poland's Chopin Airport saw an 8.7% increase in its passenger numbers in the first three months of the year.
The airport handled over 2.1 million passengers between January and March in 2015.
The airport reported that its low-cost sector registered the maximum growth, about 43.6% in the first quarter of 2014 while passenger numbers on traditional flights saw an increase of 3.1%.
The revenues of Polish Airports that operates the Chopin airport saw a rise of around 2.6%.
The airport's operating costs, however, went down by 22% primarily owing to employment restructuring and workforce reduction of 800 full-time equivalents. Currently, the airport employs around 1,400 full-time equivalents.
The company's net profit was said to be around 40.6 million zlotys, which was a 306.3% increase on the corresponding period of 2014.
Polish Airports general director and director of Chopin Airport Michal Kaczmarzyk said: "Polish Airports' performance in 2015 exceeded the goals set in our annual plan and long-term projections. Thanks to the restructuring, we managed to reduce our operating costs by 20% and triple the net profit.
"With this optimistic outlook, we can plan investment to increase Chopin Airport's capacity to over 22 million passengers per year and actively participate in the infrastructure expansion at those regional airports in the Polish Airports group that are profitable."
While the costs in the first three months saw the dip, the airport is expecting a rise in its costs in the second half of the year after the opening of its Terminal A in May which will add around ten new bars and restaurants and 15 new shops to the terminal.
