These are the 'nightmare' queues in airports after nationwide customs system outage

We know it's called the "silly season," but this is ridiculous.

International travelers arriving in airports across the U.S. have been forced to stand in crazy-long queues, after a technical glitch affected U.S. Customs and Border Protection (CBP) operating systems on Monday night.

Twitter users were busy posting images of hordes of people in airport lines, while official airport handles thanked passengers for their patience.

Flyers were delayed at airport customs in Atlanta, Miami and Salt Lake City, according to CNN, while other outlets reported airports in Washington, Boston, New York City and Fort Lauderdale were also affected.

If Twitter is anything to go by, Miami passengers seemed to have been affected the most dramatically, calling the incident a "nightmare."

10 airports to avoid flying out of during the holidays

1. San Francisco International Airport – San Francisco, California 

San Francisco International Airport is the worst airport to fly out of over the holidays. If you are flying out of San Francisco, there’s about an even chance your flight will not take off on time. According to our data, almost half of the flights out of San Francisco International Airport in December 2012-2015 were delayed. For that metric, San Francisco ranks 12th. And the average delay times and cancelation rates may make people flying out of San Francisco scream in frustration. The average delay time at SFO is 41 minutes and 3.2% of flights end up being canceled. It ranks the third-worst in the country for both those metrics. Plus, San Francisco is the ninth-busiest city for flying according to our data. Yikes!

2. Newark Liberty International Airport – Newark, New Jersey 

Used by New Yorkers and New Jerseyans alike, Newark Liberty International Airport is the second-worst airport to fly from during the holidays. This is consistent with previous research showing Newark to be one of the worst airports for connections. Newark has an even higher flight delay rate than SFO. Over 51% of flights leaving Newark from December 2012-2015 were delayed. It’s second to San Francisco in our final ranking because it’s average delay time (almost 37 minutes) is shorter than SFO’s and fewer of its flights end up being canceled (2.8%).

Just over 42% of those flights were delayed and the average delay time was almost 40 minutes. Clinton National Airport’s flight cancelation rate is the metric holiday travelers will want to be the most aware of. During the period we considered, close to 4.7% of flights were canceled.

Customs officers reportedly continued to process international travellers manually during the outage.

In Atlanta, a spokesman from the Department of Homeland Security's CBP agency, Rob Brisley, told CNN: "We can confirm that there was an outage with the processing computer that the customs officials use. It lasted about an hour at the Atlanta airport, causing delays with international passengers."

While Brisley said the cause of the outage was "still being evaluated," CBP have yet to give an official statement on the incident and what caused it.

Mashable has reached out the U.S. Customs and Border Patrol for further comment.
