The Memorial Day weekend marks the unofficial start of the busy summer travel season. Friday is expected to be the busiest day of the holiday travel weekend, according to the airport, and may break a record for passengers processed at security checkpoints. More than 85,000 are expected to pass through Hartsfield-Jackson security checkpoints Friday.
The airport aims to keep wait times under 20 minutes, but lines are longer during peak times.
Airport and Transportation Security Administration officials recommend travelers get to the airport two hours before domestic flights and three hours before international flights.
