While passengers are advised to arrive three hours in advance of their flight, some were forced to wait longer and had to be fast tracked so ensure they didn't miss their flight.
It comes after a number of airports cancelled flights and suffered long delays earlier in April as they struggled with passenger numbers due to a lack of staff.
Leeds Bradford Airport wasn't affected earlier this month, but on Saturday morning (April 30), some passengers were forced to wait in long queues while getting through security. Some passengers were waiting around 90 minutes to get into the departure lounge.
Chris Strather, Leeds, 52, who was travelling said that he “wished he’d not bothered,” but that it “wasn’t too bad.”
A staff member, who doesn’t want to be named, said that the airport is “struggling to recruit people,” and said it’s a similar case across other airports, but said LBA had been criticsed unfairly in the past.
The airport recently tweeted urging people to arrive early if they are travelling this weekend.
It said: "If you're due to travel from Leeds Bradford Airport over the next few days, please arrive at the earliest time your airline allows. You can help to minimise any delays by preparing for our security screening process."
The airport is also recruiting for a number of full time, part time and flexible hour roles as passenger numbers continue to increase.
A spokesperson for LBA said: "We are currently experiencing longer queuing times for our security process during peak travel times, for LBA this is between 5.00am and 9.00am in the morning and late afternoon.
"We would like to apologise to those impacted and we’re working hard to overcome these challenges with ongoing recruitment and training activities and more staff being released to the operation from training each week.
"Unfortunately, these current challenges are an industry wide problem, caused by the speed of withdrawal of travel restrictions and testing which has led to the rapid recovery of international travel. Passenger numbers in March were almost 3 times greater than in January and continue to grow. Airports across the country are being impacted by lead times to recruit and train additional staff.
"We are actively managing queues to pull people to the front as their flights near departure, which ensures that very few passengers have missed flights. Those impacted are mainly those who arrive at the airport late or those who have some form of security issue related to their bags.
"LBA is confident that with additional staff being recruited the situation will return to more normal queuing in the coming weeks."
