Passengers have boarded the final "flyway to HEL" from Denmark to Finland, as Finnair prepares to retire the flight number 666.
Nordic Airline Finnair has run a service departing Copenhagen, Denmark and arriving in Helsinki, Finland on Friday the 13th since 2006, always using the flight number of the beast.
Juha-Pekka Kidasto, pilot of the flight on September 13 2013, told the Associated Press at the time flying the 666 flight does not bother staff.
"It has been quite a joke among the pilots," he said.
"I'm not a superstitious man. It's only a coincidence for me. If there's some passenger who is anxious about this 666, our cabin crew is always happy to help them."
The Telegraph reports the airline is now retiring the number as they change the numbering system used across the network.
A spokesperson told the paper: "As of October 29, some of our flight numbers in our network will change and our AY666 flight from Copenhagen to Helsinki will change to AY954.
"In 11 years, we've flown 21 times the AY666 flight to HEL on Friday the 13th."
