Flight passengers may face big hurdles during Memorial Day weekend travels

A massive 45.1 million Americans are set to travel at least 50 miles from their home during the long weekend, AAA announced.

Of the millions of Americans traveling, AAA predicts 3.61 million will be flying to their destinations. That's a 2% increase from last year.

Travelers should arrive a minimum of two hours before their scheduled domestic flights and three hours before scheduled international flights, the TSA advised. 

The AAA release said the most popular destinations are Chicago, Seattle, Orlando, Denver and New York.

The Federal Aviation Administration (FAA) instituted yet another ground delay at EWR on Monday, just one day after the previous delay, with flyers' frustrations growing. 

"I'd consider alternatives to EWR like LGA and JFK until the runway reopens and ATC staffing stabilizes," said Blewett. 

"It may be more of a headache in traffic, but it seems you're less likely to be stranded for the time being."

On May 7, the REAL ID requirement took effect, requiring flyers to obtain the new identification with a star in the upper right corner in order to fly. 

Those who do not have a compliant ID may receive additional screening, which would take more time. 

A TSA spokesperson told Fox News Digital the agency continues to urge passengers to get REAL IDs or bring other acceptable forms of ID for travel. 

"Summer travel is upon us, and there is still time to get a REAL ID," said the spokesperson. 

"Passengers who present a state-issued identification that is not REAL ID compliant at TSA checkpoints and who do not have another acceptable alternative form of ID will be notified of their non-compliance, may be directed to a separate area, and may receive additional screening," the spokesperson added.
