Travelers on a Norwegian Airlines flight from Paris to Stockholm erupted in cheers and laughter when the pilot sent his best wishes to 2 passengers that had joined the "mile high club."

A female passenger told the Mirror the pilot said, in Swedish, "We'd like to send our best wishes of happy reproduction to the couple that ventured into the bathroom earlier on." She added, "People around the plane started cheering and laughing and there was a lot of gossiping about who it could have been."

Passengers who did not speak Swedish were left clueless, with the pilot simply saying, "Welcome to Sweden," in English after his congratulations.

The nationality of the "mile high" couple was not revealed and the airline declined the Mirror's request for comment on the matter.
