Make sure you’re standing in the right queue. If you have baggage, you should go first to a check-in counter and then to the security checkpoint. When it’s your turn to go through security screening, be prepared.
Get ready in order to get through faster – have your boarding card, one-litre bag with liquids, electronic devices, sharp objects and outer clothing ready.
It’s OK to pass through security screening even if your gate has not been posted.
At Terminal 5, you can go through any of the two security checkpoints as both give access to all gates.
