Here are ways that passengers can cut security wait times at Birmingham Airport, according to the Airport CEO

Travellers have frequently complained about lengthy delays, frequently standing in queue outside the terminal while they wait to be checked in before boarding flights.

Passengers are not allowed to carry two litres of liquid in their hand luggage due to a government regulation, even though Birmingham Airport has installed security measures to accommodate larger bags.

Travellers are therefore being reminded to make sure they don't bring containers that hold liquids, pastes, or gels larger than 100 millilitres, as the confusion is causing serious issues at security.

Birmingham Airport CEO Nick Barton has given information on how travellers might avoid these issues even if passengers are still boarding their original flights.

He said: "What passengers can do to help us to help them is to make sure there isn’t a single bottle of fluid or liquid or toothpaste, or whatever it might be, in their cabin bag - so the bag they take on the plane - that is more than 100ml.

"It’s a very simple message but one that we make repeatedly.

"If they can do that, their chances of getting through security increase enormously.

"If people follow their guidance about getting here in good time, but not too early, that’s crucial. Getting here very early means you join the queue with other flights that need to go before you.

"Following your airline direction about when you need to get here is important, that’s typically three-to-four hours before you depart.

"That will allow you to get your bags checked in for the hold and then you can get yourself to security in a way that we can get you through, typically in a reasonable period of time that shouldn't cause any problems.

"But, we understand the stress and anxiety that people are feeling beforehand and we are doing our very best to minimise that."

The CEO hopes that the issue will be resolved by the school summer holidays and says the airport are putting measures in place to try and reduce queuing and issues at peak times.
