Flights are generally sale places to be thanks to airport security and the work of on flight crew.
But do aeroplanes have CCTV cameras?
One curious passenger asked this question and an airline pilot revealed their professional experience.
Bruno Gilissen, who has previous experience work on four different airlines, said: “Yes, in an airliner nowadays there are cameras installed inside.
“Since 9/11, security measures dictate that the cockpit door has to remain closed and locked at all times during flight, unless authorised persons enter or exit.”
The camera is used to send live images of the cockpit door area into the cockpit, so the pilot can see who is outside.
This is to prevent highjacking or anyone without proper clearance to be in the cockpit.
The cameras not only show who is stood outside of the door, but also check if there is anyone hiding around the corner.
But what about the main body of the plane? Are there security cameras there?
Bruno said: “An optional cabin camera can be installed as well, giving the cockpit crew a general view of what’s happening in the back.
“My guess is that most airlines don’t have this option.”
Is it legal to drink your own alcohol on a plane?
Surprisingly it is. There is a way for travellers to bring their own alcohol onboard as well as drink it without breaking the airline’s rules.
Travel writer of website God Save The Points Gilbert Ott explained how to both bring it onboard and be allowed to drink it.
Bringing personal alcohol is allowed if it is under 100ml.
A travel blogger recently debunked various travel hacks.
People are advised, if travelling as a pair, to book the aisle and the window seat so they get the whole row to themselves.
“She explains that this is: “the presumption that no one will book the middle seat.
“But airlines fill flights. It’s how they make money.”
