Gatwick Airport has hired 400 extra security staff to try to ease queues during the school summer holidays.
Bosses said having the extra workers would make the airport process "as smooth as possible".
The airport is also trying to increase awareness about placing liquids in a clear bag, separate from hand luggage, to reduce delays at security.
The announcement comes amid an air travel crisis which has seen thousands of flights cancelled or delayed.
Chief operating officer Adrian Witherow said: "With passenger numbers rapidly returning to 2019 levels, we expect to be busy, particularly at peak times such as weekends and the forthcoming school summer holidays.
"We are doing everything possible to make the airport process as smooth as possible, including recruiting and training hundreds of new security staff, many of whom have already started or will be in coming weeks."
