The Devil’s Flights: Which Routes Use Flight Number 666?

Many numbers are considered to be lucky, unlucky, superstitious, or somehow unique. It varies regionally, religiously, culturally, or by country. There are also numbers directly associated with a particular event that resonates, whether positively or negatively. But what about flights that use 666, the ‘devil’s number’?

Unusual numbers

In the case of aviation, the lack of use (or indeed use) of these ‘special’ numbers as flight numbers is intriguing and telling. It can apply to a specific airline – for example no longer using the number when a flight has gone down with a loss of life – or can be broadly applied at an individual country level or more or less for the whole industry.

Routes with flight number one, for example, are often perceived as prestigious. They conjure up images of importance or difference, or they may reflect a historical point in time, a technological advancement, or the specific market or passengers.

The devil’s number: 666

What about number 666, the so-called ‘number of the beast’ and synonymous with the devil, the antichrist, or evil in general?

For some, this number is believed to hold such meaning as to scare them into taking action. In 2013, Route 666, a US highway nicknamed the ‘Devil’s Highway’, was renamed Route 491 due to the negative connotations. Surely no airline and no route would have flight number 666?

What routes have flight number 666?

In 2021, just 20 routes have flight number 666, OAG schedules show, whether they’re a one-off service or regularly operated. That’s not many – and SIN (Singapore) to HEL (Helsinki) isn’t one of them. In contrast, ‘unlucky’ 13 has twice as many flights – none within the US – while ‘lucky’ seven has five times more flights.
