The boarding pass code you never want to see – as it means you might not get a seat on your flight
BEFORE you board your next flight, you might want to check your pass before you get to the gate.
A ticket agent has revealed a certain code which if you see on your boarding pass, means you might not have a seat after all.
An Air Canada ticket agent has revealed how the code "GTE" reveals if the flight has been oversold - something most airlines do - and how it might impact passengers who have this on their boarding pass.
He told : "If someone has 'GTE' [for 'gate'] on their boarding pass, it means they don't have a seat."
The unnamed attendant also claimed that he told ticket agents for the airline not to tell passengers as they would get upset - instead, they should send them to the gate.
The revelation comes after an Air Canada employee revealed how they were trained to hide information from passengers regarding their flight ticket and whether they had been given a seat.
It isn't the only code you don't want to see on your boarding pass.
If you see SSSS on it, you could even end up being late for your flight.
The code stands for "Secondary Security Screening Selection" which means that the passenger has been selected for additional screening by security.
Anyone with this code is advised to turn up an extra half hour early for the airport, because getting through security will take considerably longer than usual.
Officials will take a particular interest in you and your luggage; giving you a pat down, swabbing for explosive residue and opening up all of your bags.
Thankfully, this usually only applies if you are flying to the US, although some passengers have said they had the code on their passes when travelling to countries such as Turkey.
Here are some other boarding pass codes you need to know about.
Don't throw your boarding pass away, however - as it could get you some extra discounts on holiday.
