While some people spend Friday the 13th avoiding black cats and ladders, there are those who laugh in the face of superstition.
Nordic airline Finnair has a flight from Copenhagen, Denmark, to Helsinki, Finland, on Friday the 13th, typically seen as a day of misfortune.
It has been plying the route since 2006.
The city code for Helsinki is HEL, and the flight's number is 666 - a number usually associated with the devil.
On Friday (Oct 13), it left the Danish capital at 1.20pm and arrived in Helsinki just before 4pm, safely.
The airline has retired the flight number, reported The Telegraph.
A spokesman said:"As of Oct 29, some of our flight numbers in our network will change and our AY666 flight from Copenhagen to Helsinki will change to AY954."
The spokesman said that the flight has operated 21 times in the past 11 years.
According to The Telegraph, pilot Juha-Pekka Keidasto said that he is not superstitious, nor was he scared about piloting the flight as it was "only a coincidence" for him.
"It has been quite a joke among the pilots," he said. "If there's some passenger who is anxious about this 666, our cabin crew is always happy to help them."
