Flight 666 to HEL on Friday the 13th.
Despite being a superstitious person's worst nightmare, the flight was reported to be "almost full," said Juha-Pekka Keidasto the pilot who flew the Airbus A320 from Copenhagen to Helsinki. Keidasto also stated that he is not a superstitious man and that it was "just another flight" for him.
I'm betting he had a lucky rabbit's foot in the storage box next to him, though.
The flight arrived three minutes early in Helsinki without incident.
