Extra flights between Cardiff and Amsterdam Schiphol airport are being added by KLM before the end of March.
More than 8,500 additional seats will be available for five weeks between February 24 and March 30.
An extra daily flight with a larger Boeing 737-700 aircraft has been scheduled for the period.
This will give up to four flights a day, seven days a week to the Dutch hub. Fares start at £87.59 return.
Cardiff airport commercial director Spencer Birns said: “The commencement of extra flights with KLM comes right at the start of half term holidays, so it’s an ideal time for our customers to benefit from great fares and book an early spring break.
“Over 30% of our passengers are visitors to Wales, so these extra flights also create new opportunities for international business and leisure customers to use Cardiff airport as their gateway to the UK.”
Air France-KLM UK and Ireland general manager Benedicte Duval added: “As a result of the strong passenger numbers on our Cardiff to Amsterdam route, we are delighted to be able to add extra capacity over this period.
“The additional daily flight will add over 8,500 seats, to provide people in the region with an enhanced choice of flight and connection times.
“As well as this, it will offer international tourists more opportunities to visit the beautiful country of Wales.”
