However, according to the airline, this will be the last time that Flight 666 takes to the skies on Friday the 13th as the airline is changing its flight numbers on October 29 as Finnair adds new flight routes. The flight from Copenhagen to Helsinki takes about an hour and half.
The flight started in 2006 and has fallen on Friday the 13th 21 times. As of Oct 29th, some of the flight numbers in the Finnair network will change and AY666 flight from Copenhagen to Helsinki will change to AY954.
Pilot Juha-Pekka Keidasto previously told RT: "It has been quite a joke among the pilots. It's only a coincidence for me", he added.
Triskaidekaphobia is the fear of the number 13, which dates back to the late 1800s.
No more superstitious flights for those fearless passengers. The flight number will not, however, be 666.
According to the Telegraph, Friday the 13th is considered unlucky because of its biblical origins, it has also been linked to the Knights Templar. And obviously, there's the entire Friday the 13th movie franchise that is the most notable.
Additionally, Finnair revealed that this isn't the first time they've journey to Helsinki aboard AY666 on Friday the 13th.
