It’s Friday the 13th, making this flight to Helsinki pretty nerve wracking for superstitious fliers as the Daily Mail points out. 

“A spooky Friday the 13th coincidence paired the widely-regarded number of the devil with Helsinki resulting in flight 666 to HEL,” reported Gareth Davies. 

The Finnair flight flew from Copenhagen at 12:25 p.m. and landed—safely—in Helsinki at 3:50 p.m. 

Adding to the superstitious factors of the flight: The plane is 13 years old. 

Despite its spookiness, the flight is incredibly popular, especially on Friday the 13th.

“The flight has been running for years, but the airline said it becomes popular whenever it lands on Friday the 13th,” reports Davies.

If passengers are worried, there is assistance. 

“It has been quite a joke among the pilots. 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,” says pilot Juha-Pekka Keidasto.
