The landmark passenger was named as Ms Monta Skābarniece who arrived at the airport on board an airBaltic flight from Munich.
That was certainly lucky as a variety of airBaltic employees just happened to be waiting to pounce on the tarmac, armed with a selection of promotional items.
“I am very pleased at the Riga Airport’s remarkable achievement – serving 50 million passengers. The number of passengers is continuing to increase, and I wish the airport to serve more than 5 million passengers this year,” said Transport Minister Anrijs Matīss.
Andris Liepiņš, chairman of Riga airport said he expected to see another 50 million people pass through the gates in "less than ten years."
Ms Skābarniece received a selection of souvenirs and some business class tickets from airBaltic.
The airport served 2,377,503 passengers during the first six months this year with the most popular destinations being London, Moscow, Frankfurt, Oslo, and Helsinki.
