Secret codes in the airplane among the cabin crew


Are you a person that travels a lot? Do you catch flights very often? If yo do, you must have notices some strange and unusual codes that the cabin crew uses in order to communicate with the rest of the colleagues. You must wonder whether you have heard the right thing or are they joking. Most of this codes are unknown for the public and the ordinary passengers. However, even though they don’t want you to know their secret codes, some people of the cabin crew reveal its meaning for the most curious passengers because they know the vast majority does not get its meaning.

5 days in Denmark

This one has nothing to do with Denmark. This one means that the person on the seat D on the fifth raw is strange, does something weird or acts unusual therefore they should keep an eye on him. Thanks to this codes the rest of the passengers don’t get that something’s wrong and they keep calm while the cabin crew does his job.

Blue Juice

There’s no blue juice in the airplane. However, just because the water of the toilet is in that very colour, whenever there’s a problem with the toilet they just share these two words and solve the problem. The rest of the passengers has no idea what’s going on.


It’s not a day od the month but rather a signal for warning. It comes from the French phrase “Venez m’aider” which means “come and help me”. They repeat the word as much as three times just to make sure the rest of the cabin crew does not misunderstand the word or confuse it with another one.


This one reffers to a mechanical defect. Its roots are French too. It is used in situations in which the people’s life and health are not in danger but, however, there’s something that has to be repared.

Code Red

Let’s hope you will never have to hear this phrase on any of your flights because if the things get serious it might mean this is the last flight you have caught. It is used in extrem and complicated situations. It might mean that the pilots are facing technical problems or even need to do a forced landing.

Number codes

7500 – it’s a radio signal that says that the airplane has been kidnapped or attacked

7600 – it means lost connection and communication

7700 – it’s a universal sign for emergency

The flight attendants claim to exist another word that follows the numbers but for the security and the safty of the passengers, they prefer to keep it a secret. It is a code-word that resonates only with that particular aircraft and cabine crew.


This code is used in a certain situation when the aircraft needs to do a forced landing over water, sea, ocean, lake or rover are in question.

Purrel, Purrel, Purrel

Purrel is a brand for disinfection, but in the aircrafts and on the boats this “magic” word is repeated three times when a cleaning service is needed. In most of the cases it is about a passenger who feels bad and there´s a need to be cleaned after them.
