"It doesn't make a difference whether you are a man or a woman when flying," the statement quoted Siriratne as saying.
"The circumstances don't change, the weather is the same, and the aircraft doesn't know the difference!"
Siriratne said women have lagged behind in the field of aviation in Sri Lanka, in comparison to the rest of the world.
"Even in neighbouring countries such as India, women have been airline Captains for many years now," she said.
Her husband Hemantha is also a pilot in Sri Lankan and received his Captain's appointment earlier this year.They are the first husband-wife pilot duo in the country, the statement said.
Druvi Perera, Acting Senior Manager Flight Operations of the airline, said it now has several more female First Officers in the fleet, and hope to see them in command in a few years.
Sri Lankan has several female managers in senior positions in most of its nine divisions.
It also has women in areas that have traditionally been dominated by men such as aircraft engineering, the airline said.
Siriratne said that commanding an airliner has been a long-standing ambition.
She took a year off from flying when her daughter Anika, now five, was born.
Siriratne joined SriLankan as a Cadet Pilot in June 1998 and served as a Second Officer on the Lockheed L1011 Tristar fleet.
In 1999 she was promoted to First Officer when the airline was phasing out its aging Tristars with the advent of the all-Airbus fleet.
She became a First Officer on the A320's, A330's and A340's, flying to cities throughout SriLankan's network of destinations in Europe, the Middle East, and Asia.
She obtained her Private Pilot's License at the local flying training school, CDE Aviation, and her Commercial Pilot's License in Texas.
Before joining Sri Lankan, she had a short stint as an Instructor at Sky Cabs, another domestic airline.
