Flight tracking account Flightradar24 also poked fun at the coincidence, tweeting: "Would you dare to sit in row 13, on board Finnair flight 666 en route to Hel on Friday the 13th?"
The final destination for passengers on this Friday the 13th flight is HEL.
Nordic airline Finnair has flown courageous passengers from Copenhagen, Denmark, to Helsinki, Finland, on Friday the 13th since 2006.
The Helsinki airport says Flight 666 has arrived safety in HEL - the airport code for the Finnish capital - for the last time.
This is the 21st time the flight has taken place on Friday 13 since the operators started the AY666 route in 2006. But the move has nothing to do with superstition: "We are a growing airline and we are reorganizing our flight numbers to make room for additional flight numbers to be used", an airline rep tells the Independent.
Due to depart at 1.30pm, the flight will last around an hour-and-a-half. I'm not a superstitious man.
The last time the flight happened on Friday the 13th was in January.
'If there's some passenger who is anxious about this 666, our cabin crew is always happy to help them'.
The irrational fear of the number 13 is called triskaidekaphobia, by the way.
Finnair insists it isn't scrapping the spooky number because of fears from superstitious customers.
