This isn't a joke - it's actually a little creepy.
In a real-life coincidence, a flight taking off from Copenhagen to Helsinki on Friday had some very Friday-the-13th related information attached to it.

Finnair Flight 666 took off from Copenhagen (CPH) and landed in Helsinki (HEL) on Friday. Friday, January 13.
The flight took off at 13:00 local time. And landed at 3:41 HEL time.
Flightradar24 even pointed out that the plane is 13 years old.
And no, no "Jason" was listed on the flight list.
