Passengers prepare to board flight 666 to HEL on Friday the 13th

HELSINKI - Finnair passengers on AY666 to Helsinki

, which has the three letter designation HEL, don't seem too bothered by the flight on Friday the 13th. Friday's flight is almost full.

Finnair pilot Juha-Pekka Keidasto, who will fly the flight from Copenhagen to Helsinki, says "it has been quite a joke among the pilots."

Friday the 13th is considered bad luck in many countries and the number 666 also has negative biblical associations.

Some airlines take these fears seriously and don't have seat row 13 on board.

However, the negative connotations of Friday the 13th are a relatively new phenomenon for northern Europeans and Finnair keeps row 13.
